operating system not supported Error code 45056

Avast Free Antivirus / Premium Security
1

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
