“.apa is not a valid archive file.”

I recently tried to put a Factory Talk View file onto my computer and the message comes up with: “.apa is not a valid archive file.” Has anyone had the same issue and what is the best fix for it ?

What version is the archive from and what version do you have on the PC(And is it 64bit)

Also, you should be able to open the .apa using 7-zip. There is a file in the root called TargetPlatform. See what that says as .apa is the archive extension for both ME and SE applications. Need to tell the Application Manager what 'type' it is, can't just double click the file.
