I can’t execute Autochk on prymary SSD (Win7 32 bit) I have this error:
(766f6c756d652e63 3f1).
I can execute Autochk on secondary HDD.
If I uninstall AVAST antivirus I can do Autochk on primary SSD without error!!!
Thank you

I checked in variables environment the PATH, and I had a wrong path from one software I uninstalled.
I deleted manually this and now also with AVAST free installed the autochk is OK.
May be this can help someone!!!

Geez! I have exactly the same problem on my Media Center. Everything was running fine before Windows 10. After upgrading, I decided to downgrade back to Windows 7 32-bit (original OS with MS Media Center), but after installing all software I received exactly the same error message yesternight. Too late, I re-forammted the complete hard drive. Now I will re-check after Avast 2015 installation.

It seems like there’s something wrong in the avast installer 2015 for Windows 7 32-bit, I never had this problem before (I upgraded since first installation in 2010).

Thanks for your help, I’ll come back and tell the (hope good) news.

Well… after second format and re-installation, everything worked fine. “Windows”, nothing else to say… :stuck_out_tongue:
