VisualD installer doesn't detect Visual Studio 2022 installation when it has a nickname

[gmueckl]

Recent versions of Visual Studio allow multiple parallel installations for the same version (for example, 2022 Pro and 2022 Enterprise can be installed at the same time, see [1]). The installer prompts the user for a nickname for any additional installation, which cannot be changed later [2]. This nickname gets appended in paranthesis to the DisplayName key in the corresponding uninstaller registry key. For example, I have an installation named "Microsoft Visual Studio Enterprise 2022 (2)" because it was a secondary installation at some point in the past. At least VS2022 and VS2019 support this feature. I don't know if support goes back further.

The VisualD installer script looks for Visual Studio 2022 comparing the last 4 characters of the display name with "2022". This fails with a nickname present and the Visual Studio 2022 checkbox gets disabled. I think a better algorithm is to ignore anything after the first " (" in the display name. Of course, this has the unpleasant side effect that the user would ultimately need to get a choice of installing VisualD for each parallel Visual Studio installations if this side-by-side installation situation is to be supported properly.

Unfortunatenly, my NSIS scripting skills are not good enough to fix this issue myself. Otherwise, I'd be working on a patch already :(.

I guess vswhere (https://github.com/microsoft/vswhere) can detect all installations, so it would not be too hard to get a list of them all. Making NSIS show and execute this list dynamically is probably a nightmare, though.
