I have a project that was developed many years ago using Visual Studio 2011 and embedding Installshield to compile distributable copies. I need to enhance it so I have opened it in Visual Studio 2022. I can run it in debug mode so I'm happy that it works, but I can't create a distributable copy because Installshield is now obsolete.

I think I should be able to use Wix as an alternative to Installshield so I have added the Heatwave extension to VS2022. I made a copy of the project and opened it in the modified VS2022. However, when I try to compile the programme I get errors:

Until I can resolve this I can't make any progress on achieving my aim.

Any suggestions why it works with VS2022 but not with VS2022+Heatwave?

The original project still works on another laptop running VS2022. I made a copy of that project and ran it on VS2022+Heatwave and it generates compiler errors
