Ok, trying to recover my network from last weeks update bug. I have a Vista workstation that would not apply the patch so I did an add/remove programs and took KAV off and tried to reinstall it and I get the error message that I have attatched. This is version 6.0.3.837. Can anyone give me any help with this?

Please try msicuu2 from Microsoft.

Thanks for the tip. Tried it and no success.

Look here.

No luck with that either.

Also noticed when I tried to install a free av for some protection till this started working that it said I already had an AV isntalled. So, I think there is a part of KAV still on this computer. Is there a tool to remove all of KAV like Symantec's nonav.exe?

Still no help with this problem? Does anyone know how to completely remove KAV so that I can reinstall? Already did add/remove programs on it and there is still something there. Service is gone from my service list.

Hello,
do you have allready tried this?: http://support.kaspersky.com/faq/?qid=208279752
P.S: boot in save mode an run this tool
kind regards

That tool says that my application is not detected.

open regedit an look for these 2 registry keys:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\avp6_post_uninstall]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\avp6_post_uninstall]
if these 2 keys still there, remove the keys, and try to reinstall the 6.0.3.837 WKS
best regards

Those two keys are not there.

okay,
