ReSharper stays in the list of installed programs after Visual Studio is uninstalled

Problem

After a Visual Studio version is uninstalled, the ReSharper record for that Visual Studio version stays in the Windows list of installed programs. Uninstalling the record does not remove it.

Cause

ReSharper keeps its installation data for each Visual Studio version in a separate folder. When Visual Studio is uninstalled first, the ReSharper record for it is left without a working uninstaller.

Resolution

1. Close all Visual Studio instances.
2. Open the %LocalAppData%\JetBrains\Installations\ folder.
3. Delete all subfolders whose names start with the prefix for the uninstalled Visual Studio version (see the table below).
4. Press Win+R, enter appwiz.cpl, and press Enter to open Programs and Features.
5. Select the record named JetBrains ReSharper in Visual Studio <edition> <version> for the uninstalled Visual Studio version, and click Uninstall.
6. When Windows reports that the uninstaller is missing and offers to remove the record, accept.

To free disk space, also delete the ReSharper caches for that Visual Studio version: %LocalAppData%\JetBrains\Transient\ReSharperPlatformVs<NN>, where <NN> is the number from the table.
