I have a clint with the following:
Win 7 x64, 300 GB HDD, 4 GB RAM. He uses the program Calyx 7.2 for his business. Issue is as follows: Files are unable to be opened due to encryption (all in green). Working with Calyx Support, they gave up and laid it at Microsofts door. We were able to remove Read Only and File Encryption on some files and folders but not the hundreds of files necessary for the user to see the mortgage info he needs. I have shut off and turned back on ntfsdisableencryption in the registry. Did not help, Calyx Support went after it with everything they could come up with. Files cannot be unencrypted due to permission issues. All files and folders have God privledges so copying, deleting, etc. should not be an issue, but it is.
