On a Vista 32 bit system (that dual boot_s to a MultiPoint server) I am stuck with half an installation of BD Internet Security 2013. If I try to reinstall I am told that the product is already installed, I then continue anf get get the attached error. There is no uninstall option in Programs & Features so I downloaded and ran the 2013 uninstall tool from both normal and safe mode then rebooted.
Now I find that DNS is not working. I can PING anywhere with an IP address but URLs are not resolved. It appears that any form of Internet access except web browsing is OK. I have tried with different browsers including IE with no add-ons in Safe mode. My only way to recover this function is to use system restore.
After the uninstall runs I am left with unaccessible files under Program Files (even if I mess with ACLs to take ownership) and the registry is stuffed with references.
How can I completely uninstall then properly install please ?
