InstallAware

In Visual Studio 2019, Community Edition, I tried to create a C # program installer that uses the "Syncfusion Windows Form" libraries, and I have this result:

if I Run Setup:

Generating setup project for active solution (Any CPU platform)
Main Script File CS4D.mia was not regenerated. No change was found.
Project File CS4D.mpr was not regenerated. No change was found

Thanks in advance,

It's always a good practice to not include into the project, source files from system restricted folders (ex; Program Files, System and so on).

Make a copy of all your source files, store all them into separate NEW folder (ex: ProjectFiles). Finally From IA, replace any existing reference to those files with their copies from the new folder.

Last but not least, even projects should never be stored under system restricted folders, or at system drive root level ("C:\QSync\Programmazione\.."). The best approach is to have a dedicated drive for projects. When this isn't possible, at least use the Document folder or similar.
