Version : 1.8 / 1.9 / 2.0

Possible Reason :

The WinRAR version or AutoCount version used to create the backup file is newer compared to the AutoCount version used to restore. WinRAR version 5.50 has compatibility issue with Auto Count program and this issue is solved in version 1.9.6.21.


Solution :

Update AutoCount to version 1.9.6.21 or later that supports WinRAR 5.50 or later.

Release Note 1.9.6 (Revision 21)
