I had to reinstall SKP Pro 2016 after a mishap associated with upgrading from Win7 to Win10. After getting all the extensions reinstalled, I notice that the load on demand function in the Vray Tools extension is greyed out and not working anymore. This is a big problem because I’m sharing my Vray plugin license pool with hundreds of other people and can’t keep it checked out all the time. Anybody else have this problem? Is there a fix? ---

I am not sure why it is grayed out, but check if **V-Ray For SketchUp** is already loaded and the toolbar is hidden or closed? What are you seeing in your extensions list? ![](https://global.discourse-cdn.com/sketchup/original/3X/0/0/00e0df35ded4188a2cf96060b2e71676c3de0db6.png) you should ideally see **V-Ray For SketchUp** checked off ---

Yes. Vray is installed and working. But the Vray Tools load on demand option is still greyed out. ---

But for Vray Tools to work, make sure Vray is **NOT** checked in the extension list. (I meant “off” as “not checked”.

Ah. I understand. That seems to address the problem. Thank you. ---

BTW, that’s how Vray Tool is supposed to work. It has been the same for any OS and SketchUp versions. ---

It would be helpful if that was actually documented somewhere. I’ve been using SKP with Vray and Vray Tools for about as long as Vray Tools has existed, and this is literally the first time this problem has ever come up. ---

That is very odd, because just installing the Vray Tools won’t work. Somebody you or whomever using the machine must have it set up to disable Vray in extension list to work properly. ---

> [@thomthom](#): > > The good news is that V-Ray for SketchUp 3 will make this extension redundant. 😃 Haha, i am not sure if that information is public yet? and perhaps one needs to pay the upgrade fee for it. 😛 Anyways, there was an issue with Vray 2.0 which the disabled become enabled again when two SketchUp was opened simultaneously. I have heard that this is their issue, and they see that version 3 will the ultimate fix for it. ---

If you open the second SketchUp after the first finish loading, its fine. Just don’t load them together. > [@SketchUp multiple launch triggering disabled extensions](http://forums.sketchup.com/t/sketchup-multiple-launch-triggering-disabled-extensions/22883): > > I have SketchUp 2016 M1 version, and this is something new in 2016 which didn’t happen in 2015 or older. Disabled extension seems to get enabled again when SketchUp is launched multiple times. (The second launch has to happen whilst the tools are loading) I can go back and disable it again. Which seems to stick, but when I launch more than one SketchUp file, it seems to come back (I have to open multiple files often in my workflow) The extension that has this issue, is V-ray Extension.
