Application can't open file on read-only USB drive
Can you please support me in resolving the following issue with SEP12:
When Application and Device Control policy makes USB drive read-only, Excel can't open files stored on USB drive.
I use following Application and Device Control policy:
It is copy of default Application and Device Control policy with enabled controls "Make all removable drives read-only [AC3]" and "Block writing to USB drives [AC4]"
Excel shows error "Microsoft Excel can't open or recover book because it is corrupted" when opening .xlsx file located on USB drive.
If this file is copied to local drive, it can be successfully opened.
Log of local SEP12 client, showing that writing is blocked is attached (Control Log Read-only USB drive.xlsx).
Same functions work fine in SEP11.
What must be done to make USB drive read-only and make files on it accessible by applications like MS Excel?
