Problems with installation

Windows Vista Home Premium.

After installing Comodo Pro v3.0.13.268-32bit, Vista (after reboot) warns of an “unauthorized change to windows which may result in limited functionality” and it logs me off, refusing to let me log in at all.

Anyone else encounter this before? Are there any fixes for it?

So far the only solution is to uninstalling it.

Thanks in advance for any help here.

I appreciate that you have a problem of your own, but please try not to hijack threads this way. It only gets in the way.
