Hi,
For one of our project, we had created some registry entry under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID<registry entry> and some under specific VS version. This seems to be working fine with VS 2015 or prior releases. From VS 2017 on-wards we have moved VS specific entries in *.pkgdef file. But we are not exactly sure about registry entries for CLSID. If we make under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\ it does work with VS 2017 but our doubt is on system where multiple instance of VS 2017 exist will it work ? Or we need to move these inside *.pkgdef file ?

    Hi @Archana Soni ,

    Welcome to Microsoft Q&A!

    Do you want to detect the instances of Visual Studio 2017?

    Changing registry entry of Visual Studio is not recommended. You can use Tools for detecting and managing Visual Studio instances.

    In addition, the details of existing Visual Studio instances are located in C:\ProgramData\Microsoft\VisualStudio\Packages_Instances. You can also check it.

    Sincerely,
    Anna
