Unknown Software Exception

Avast Free Antivirus / Premium Security
1

I am unable to install Avast on a laptop. Every time it installs, it always says that it was successful but every time I try to open Avast, I always get

"[i]the exception unknown software exception (0x40000015) occurred in the application at 0xf97ce76f.

Click OK to terminate the program[/i]"

I tried countless repair installs and clean installs but the error message persists no matter what I do

Googling the message only brought up 2014 results. There is absolutely nothing recent or even from 2018, the latest result on this error message is December 2014

  • Which Avast…? (Free/Pro/IS/Premier)
  • Which version…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Premier/Latest version/Windows 7/AVG (long ago)

I needed to reinstall because the same thing that I mentioned the other day with the “unexpected error” happened on my second PC. Has not happened on the third (yet)

Windows 7 SP1? If you are not at SP1, Avast does not support original Windows 7 version.

Example: Do you have iOBit installed?

If good, then
