ac800M backup opening problem

You can modify the installation of compact control builder in the control panel and enable coexistance with older versions. This will install older versions of the standard libraries on your PC.
If you have imported 800xa 5.1 control project into clean 800xa 6.0 system. Where 800xa 6.0 system doesn't have Basic HW lib 5.1. To open this project in 800xa 6.0 you have 2 option.
Option 1 : Restore the system 800xa 5.1 maintenance backup to 800xa 6.0 and then it will allow to open the control project and then you can replace the Basic HW library to 6.0 as a part of upgrade.
Option 2 : Export Basic HW 5.1 and then import the same into 800xa 6.0 and then open this control project, once you successfully open the project then later you can remove Basic HW 5.1.

The Backup of your project is from 800xA5.1 Rev C , this version is having BasicHardwareLib-5-1-0.hwl, if you try to import in 800xA 6.0.X version it will give the error as per your screen shot.
I had checked the same and getting same error when I tried to open the project created in CCB of 800xA5.1 Rev C in 800xa 6.0.0-1
As per mpetter78, you can change the installation of compact control builder in the control panel and select “Modify"
After opening the project, it will ask for upgrade,Automatic pop-up for saving the project & Hardware libraries upgrade.
Once upgraded, Hardware libraries will get changed and shows upgrade project finished.
