I purchased the annual student version of light up right after using the demo version. I tried entering the registration key but it said that it was invalid. I then followed what it says in a thread to download the uninstaller for the demo version but as I tried opening it, it said that the file was damaged. Any suggestions on how to use my paid student version after using the demo version? I'm a Mac user, btw.

LightUp-v33c is the last version I bought, I haven't been able to upgrade yet. I do use Sketchup 2016 though. Am I right in assuming that I cannot install 33c for use in 2016?

The installer doesn't give any error messages, but also doesn't install it into the plugins folder. I also don't get an .rbz file to use via "Install Extensions...".
How do I proceed, or is it just not compatible anymore?

Regards, SAM.

SketchUp2016 moved to 64-bit so you will need to 64-bit version of LightUp. It also introduced .rbz installers.

So you can login, go to Downloads and click 'Buy or Upgrade' to purchase a discounted upgrade to LightUp v5.

What's an Mray?

I'm trying to figure out why it's taking 4 hours to render my sketchup file.

i need an answer to this question

Chan P's picture

i ve download demo version few days back and decided to purchase LightUp.
downloading and follow instruction as given, still have domo vesion in my sketchup.
what must i do to get LIghtup working for me, thanks.

Adam B.'s picture

When you purchase, you get a new Installer AND a new RegKey.

Just to be sure, remove the DEMO version by opening File Explorer and in the textbox, type:


and navigate to Roaming/SketchUp 2016/Sketchup/Plugins

to remove the lightup file and lightup folder.

Launc Sketchup and confirm there is no LightUp before using Preferences->Extensions, Install Extension...


Hello I have just download the trial lightup V5 for Sketch Up 2016 - received the demo / RBZ. but when opening I received error quoted as

" SketchUp was unable to install the Extension you have chosen for some unknown reason.

Consult your Extension's documentation for additional help. "

Please advise how to proceed, thank you.


Adam B.'s picture


The (not very helpful) SketchUp message indicates you have another copy of LightUp installed.

Run the Uninstaller for all the old LightUp installs, launch Sketchup to confirm there is no LightUp and then use Install Extension again.


Where do I find the uninstaller?

Thank you,


Adam B.'s picture

Control Panel, Add/Remove Programs

SketchUp is telling me my activation key is invalid. What should i do?


Adam B.'s picture

invalid or Expired? If it says Invalid, it means the RegKey you are using does not match the installed version of LightUp. Carefully check that the version of LightUp you downloaded is the one you install - if your Downloads folder has older installers, its easier to choose the wrong one.

If it says Expired, you'll need to visit the LightUp website to renew the license.

Is it possible to install Light up trial to a Sketchup pro trial? I downloaded Lightup & it came as a .pkg plus 3 x bundles not as a .rbz file so I'm unable to install the extension in my Sketchup pro free trial. I downloaded the trial from the Lightup main website. Could anyone advise the best way to instal Lightup trial in a Sketchup Pro trial if possible?


Adam B.'s picture

Hi Claire,

LightUp for Macintosh is still using our original LightUp installer. Just run the .pkg installer and the files will be copied to the correct locations.

LightUp supports SketchUp Make and Pro from version SU8 upward.

How to install it... I have not setup... I have rbz file of lightup... what I can do.... please help...

Adam B.'s picture

Yes, we recently transitioned to using the SketchUp built-in Extension installer rather than our own installer.

.rbz files are SketchUp Installer files.

So Uninstall ALL versions of LightUp using Add/Remove programs from Control Panel.

1. Launch SketctUp 2016

2. Open menu Window->Preferences

3. Click on Extensions

4. Click on “Install Extensions…”

5. Choose the .rbz file you downloaded from LightUp.

Est il possible de faire varier la puissande des éclairages IES ? je n'y arrive pas
merci de votre réponse


Adam B.'s picture

In PointLight dialog, change "LLF" from 1.0

LLF = Light Loss Factor

However, you can enter a value > 1.0

Adam B.'s picture

Are you running an old version of LightUp perhaps?
The latest version is v4.6h which is shown at the bottom of the Preferences dialog.

Dear Adam,

I am working in an extremely large sketchup file, approximately 130MB. Sketchup quits when I try to 'GO' with Lightup. I am able to use Lightup with smaller files (15MB), but the rendering time is still very slow--even placing a light has lag time. I am using a pretty decent system with a Xeon processor, 32GB of RAM, and Nvidia quadro K4000 graphics card with 3GB of VRAM. Do you have any explanations as to why I am having troubles? Or should I just quit while I'm ahead.

I should also mention that I have only installed the 64-Bit Demo...

Thanks you for your time,


Adam B.'s picture

Lighting time is a result of how much lighting is needed. Check your Resolution is set appropriately; perhaps watch this video:https://www.youtube.com/watch?v=ywyI0vJNNzQ

Alexis S's picture

Hi Adam,

I watched the video, but my issue is more related I think to the fact that IF my model renders at whatever resolution -- I stress the 'if' because most of the time it quits or is too slow for my design timeline because my model is so large... even if I only place a single light -- I am not able to navigate inside my model without sketchup completely freezing. I think this program would be perfect for my purposes (as I design and mock up interior spaces for an interior design firm), if I could only get this to work faster and without freezing.

I think my question becomes this:

Is the size of my SketchUp file responsible for this issue? If so, is there a way to remedy this without losing content within my model? If not, can I improve my computer's hardware in order to acheive this?

installed light up v4 6E . i am running SU 2016. STILL ON WINDOWS PREFERENCES ON EXTENSIONS I DO NOT SEE LIGHT UP.

Adam B.'s picture

OK, if it is not shown by SU2016, then you have not installed LightUp in the copy of SketchUp you are running.
Where do you have SketchUp 2016 installed?
Where did you install LightUp?

Alok C's picture

SU2016 is installed in c/programs/sketch up
And light up in c/programs/plugins

Adam B.'s picture

LightUp is a plugin for SketchUp so needs to be installed in the SketchUp Plugins folder.

The LightUp installer discovers this folder automatically and sets it up as the location to install LightUp. Did you change it perhaps?

No matter, run the LightUp installer, it should give a default install location which you should accept and not edit.

Alok C's picture

Adam I think I am too dumb or My computer is. I have done all these options. Lightup automatically installed in programs/plugins. which did not work the first time. i manually installed in SU 2016 plugins folder and still does not work. i think i will hav to give up on this extension.

from start downloaded lightup for 32bit SU2016 . (i am using O.S windows 10)
automatic installation in c/programs/plugins.
i deleted and installed in c/Sketchup/plugins. didnt work.
deleted and reinstalled it for automatic installation . still doesnt work. please note iam running the setup file of lightup from my desktop.

Adam B.'s picture

SketchUp 2016 is 64-bit. You need to also run LightUp 64-bit installer (LightUp_x64.msi)

Thank you for your feedback, LightUp is installed by many thousands of users each month so I'm really not sure what is going on.
Perhaps it may be simpler to resolve if you use the LightUp support email help@light-up.co.uk

how much space does it take up

Adam B.'s picture

<2M bytes

yamuna k's picture

I downloaded lightup.. but I cant find plugin option or lightup option

Adam B.'s picture

Open menu Window->Preferences->Extensions and check that "LightUp Tools" is checked.

Laura M's picture

I have installed LightUp into the only sketchup version I have ever had and there is no "LightUp Tools" in that location.

Adam B.'s picture

What version of SketchUp are you running? Which LightUp installer did you use?

Laura M's picture

Make 2016. I originally used the 64bit installer since my SU is 64bit, but when that didn't seem to work I unistalled it and then installed using the other one.
Also, in Preferences/ Extensions clicking "Add Extension" results in a window to browse for a .rbx file, whereas in the LightUp folder there is only a .rb file which the browser will not allow me to choose. There is no option to change the file selection from .rbx to all file types.

Thanks for your help and I look forward to using LightUp.

Adam B.'s picture

If you are using SU 64-bit, you will need to run the LightUp 64-bit installer. The LightUp installer will default to installing LightUp for SU2016 (or the highest version of SketchUp you have installed).

NB LightUp is not a simple Ruby script, so requires a full Installer to be run - you cannot use the .rbx install from inside Sketchup (aka Add Extension).

Once you've run the LightUp_x64.msi installer, launch SketchUp and go to menu Window->Preferences->Extension and ensure the "LightUp Tools" is checked. [For all versions of SketchUp prior to 2016, this was automatic, but 2016 seems to sometimes need you to check the Extension to enable it.]

Alok C's picture

i have downloaded lightup but i am getting a message of " this installation package is not supported by this processor type. Contact your product vendor". i am working on windows 10, 32 bit on SU2016

Adam B.'s picture

Inside the LightUp download are 2 installers:

A 64-bit installer called LightUp_x64.msi for 64-bit SketchUp,

and a 32-bit installer called LightUp.msi for 32-bit SketchUp

You will need to run the 32-bit installer.

Alok C's picture

sorry Adam. from the key delivered to me it has downloaded 2 compressed files "lightUp-x64" and lightup.

the second file after unzip gives a pop up that you must unzip the lightup installer dowloaded before installing

Adam B.'s picture

Yes, you need to unzip the download onto your harddisk. What you are doing is double clicking on the download and Windows is peeking inside and showing you the files (as if its been unzipped).

You need to actually move the files out of the zip download to somewhere and run the installer.

I downloaded the software and the computer says it's installed but I can find it or open anywhere. How do I open LightUp?

Adam B.'s picture

By default, LightUp installs for the latest version of SketchUp you have installed on your PC.
So if you've tried SU2016, it will mean LightUp will install for SU2016.

If you are running a different version of SketchUp, just run the installer again and amend the install location.

For Macs, LightUp installs for all versions of SketchUp.

Joe R's picture

I'm having the same problem. There's no menu option to open the plugin and it doesn't appear anywhere on my mac

Adam B.'s picture

What version of Sketchup are you running?

Open the menu SketchUp->Preferences->Extensions and ensure the "LightUp Tools" is checked.

Extensions: 3
Adam has been using SketchUp since version 4 when he was working in the video games biz at Criterion. LightUp grew out of the desire to marry video game realtime graphics with the great usability of SketchUp.
