Uninstaller Error
What could cause the message "Uninstaller Error" - "An error occurred while trying to remove MyTestProgram. It may have already been uninstalled"?

What's got me confused, is that the registry looks perfect, if I look at HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\MyTestProgram\UninstallString, it correctly points to the uninstall.exe that NSIS created for me, and if I run that program manually from the command line, it runs perfectly.

Depends shows the uninstall.exe has no strange dependencies, plus if I change the "UninstallString" registry entry to point to the Windows calculator, I get the same error, so it's not the uninstall.exe.

What else could the control panel be having problems with?

Thanks,
Chris

When do you get this error? at start or end of process?

I'm guessing its at the end, windows will usually give some error if you did NOT remove the uninstall info from the registry
