Will not update or uninstall - "... stub cannot run ... avast.setup (code 0x3)"

[REDACTED]

I'm getting this error when I try to upgrade Avast 8. Did some digging and tried the AvastClear.exe, but same error: "The stub cannot run installer/updater executable 'c:\program files\avast software\avast\setup\sfx\avast.setup' (code 0x3)".

From further research, I ran frst64.exe - and I've attached the resulting text file. Thank you!

Please post the Addition.txt file IF it was made during the scan.  If the scan did not make the Addition.txt file then please rerun the scan with the following steps:


We need to get a fresh scan from FRST.

• If you still have the Addition.txt file on your desktop, please delete it now.
• Right click the FRST file on your desktop and select "Run as Administrator..." (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
  
• If an update is available, the program will inform you and download the update.  Allow it do this please.  Otherwise, just wait for the "The tool is ready to use." message.
• Please check the Addition.txt in the Option Scan section of FRST.
• Press the Scan button.
  
• It will produce a log called FRST.txt in the same directory the tool is run from.
  
• Please copy and paste log back here.
• The tool will generate will another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.
