operating system not supported Error code 45056
« on: January 25, 2021, 12:12:17 PM »
Hi I have paid for Avast Premium, and now that I try to load it I get the message above.
It also says to check C:\ProgramData\Avast Software\Icarus\Logs\sfx.log which I cannot find
I am running Windows 7 home premium 64 bit.
I had the free version working OK, I also tried deleting the free version program and re-booted with no joy
Any help gratefully received
Many Thanks
Dave

- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?

Hi Asyn
Thanks for the reply
Version/build? Whatever was on the website, is there a choice?
OS, as stated Windows 7 Home premium 64 bit
No other security installed
As stated, used free Avast with no problem
Many Thanks
Dave
