New Program Update ???

The latest Program Update to Avast has left it with no way to access the UI-See Attachment 1
Only one account on this computer and has full admin rights
UAC-OFF

No way to uninstall either, same error as above

Windows Vista HP x64
Malwarebytes
SUPERAntiSpyware
Both are still active and accessible

What os/sp?
What exact version of avast?
Already did a repair and/or a clean installation?

Avast advised me of a Program update, proceeded with Update.
Ask for Restart, did so.
After restart, No access to Avast UI nor able to uninstall/repair in Programs & Features

Had to check on my Windows 10 TP for Program & Def UPdate, was updated as approx. same time.
Virus Def-141125-1
Program version-2015.10.0.2208

Not surprising if you have problems when running Windows 10.
It is not supported until the final release.

I HAVE NO PROBLEM ON WINDOWS 10

The Issue is with WIndows VISTA HOME PRE 64 bit SP-2 Update

What exact version of avast?
Already did a repair and/or a clean installation?

Eddy, are we going to have to get you some glasses, eh???

Did a Re-install OVER the Top of the messed up version.
Present Def v-114125-1
Program v-2015.10.0.2208
All now seems to be working correctly

NOTE:
Avast 2015 is working in Windows 10 TP
