FAQ:
- I get " this application wont work on this computer" when running Unity.exe

You don't have all the files from the repository. This project uses Git Large Files Support (LFS). Downloading a zip file using the green button on Github **will not work**. You must clone the project with a version of git that has LFS. You can download Git LFS here: <https://git-lfs.github.com/>. 

- When installing the DXR project template I get this error:

<img src = "https://github.com/Unity-Technologies/Unity-Experimental-DXR/blob/master/documentation/Error0.png" >

This is due to Windows limitation that can't handle more than 260 character for filename. 
Please use a shorter folder and project name to allow the template to install correctly. Like "C:\DXR"
