How to collect ReSharper installer logs

Background/Situation

Installation failures for ReSharper and other dotUltimate products require the installer's own log files, not the ReSharper log or the Visual Studio log.

Question

How to collect ReSharper installer logs after an installation failure?

Answer

1. Locate the installer log folder: %LocalAppData%\JetBrains\Shared\vAny\Installer.
2. Archive the folder contents into a single .zip file.
3. Upload the archive to the JetBrains Uploads server and share the Upload ID, or attach it directly when contacting ReSharper support.

If the installer reported success, but the log folder is empty or missing for the current user account:

1. Rerun the installer with the /LogFile=<path> parameter, for example /LogFile=C:\path\log.txt.
2. Share the resulting log. It shows which user account the installer ran under.
