Older Alibre Files greyed out

[myeager]

I have a large number of AD_PRT files that I often update and modify. It appears v27 64bit will not open files older than the middle of 2023. When I click on them in the Open dialog box, the Open button is greyed out. What's the issue? Thanks.

Basics first - check file properties in Windows, have the files been marked as 'read only' or do they need to be 'un-blocked' ?

v27 should not have any problem opening older files.

Yes, thanks so much. Files that were copied onto this lap-top were read-only, while files created on this laptop were fine. All fixed.
