Is Cobian Backup compatible with Windows 8.1?
No, Cobian Backup is not compatible with Windows 8.1. This version of Windows has been released recently. The developer will update it soon. You can either check back later on its official website or install the Windows 7 version. I believe it will work in Windows 8.1.
I tried the Windows 7 version of Cobian Backup in Windows 8.1. Whenever I shutdown or restarted Windows the program stopped working.
