This is an error most people will have seen before. However, if you haven’t, it can be a bit puzzling.
You’ve created an installation, installed your application during testing, and you see this error, “The application failed to initialize properly.”
The error is usually due to a Windows system that does not have .NET installed. I have generally seen it on Windows XP systems. Actually, I can’t remember seeing it on any other Windows systems, just XP.
The fix is easy. Just add the proper .NET Framework redistributable to your InstallShield project. Rebuild, test, and watch the error go away.
