Hello,
Still applies, so what you need to do is upgrade to VS 2010 or 2012, run the install package from the download page to integrate into VS 2010/2012 then open your project up and recompile using the new version 13 assemblies.
Now deploy your app and CR 2010 runtime onto Windows 8 PC's Only version that supports Windows 8.
As for removing the MSI don't know, it's not support platform so we've never tested the uninstall.
Only option may be to FDISK and reinstall everything.
Good luck
Don
