After upgrading from Visual studio 2019 v16.9.5 to 16.10.4, the installer project file which includes two parts won't load the main project file which has the list of files to install, etc. When I try to load the project with dependencies (or not with them), I get this error but no details to figure out what is causing the problem.
Unsupported
this version of visual studio is unable to pen the following projets. The project type may not be installed or this versionof visual studio may not support them, etc. When I look at the log, it doesn't have anything specific as to the cause. How do I fix this? Help!

Hi, @Kang, Steve
May I know if you have got any chance to check my reply? Please feel free to share more detailed information to us and it will be very helpful for us to better work out this issue.
Hi, @Kang, Steve
You can try to install this extension and then open the project.
Hi PengGe-MSFT, yes, your suggestion resolved this issue. Not clear why the later version of the VS can't open files that was created by an older VS but thank you.
Hi, @Kang, Steve
I am glad to hear that.
