Hi all, I keep getting a Windows installer pop up window saying ‘preparing to install…’ and nothing more each time I boot into Vista. It only pops up then. I’m pretty confident it has to do with a corrupted installation of Symantec NIS, since I was unable to install it automatically and thus had to do it manually (deleting files, cleaning registry…)

I’ve tried disable the Windows Installer service but to no avail. I’ve also tried Microsoft Windows Install Clean Up tool, but the offending installation doesn’t show there (I guess it’s due to having removed it by hand).

Any help will be highly appreciated.
Thanks!
Oh sorry I meant I was unable to *uninstall* Symantec NIS automatically, that’s why I deleted it manually. I’ve done the registry cleanups with CCleaner btw.
