On Windows 7, I installed the QNX IDE qnxsdp-6.50.-xxxx-win32. The install failed. I tried to rerun the installer, but 
that failed because the IDE was still installed. There is nothing listed in programs and features, so Windows uninstall 

is not an option.

I tried QNXWinCleanup, which did not fix the problem. There's nothing in the registry that looks like a QNX msi package,
 and I don't know the package guid, so can't msizap. Anyone know how to resolve this? TIA
