Win XP SP2 - TI 11 Home, build 8053. Today I got a TI 11 CD and installed the program. I created an image of the C partition, stored it on an external USB HDD and verified it. Then I tried to Explore that image and got: "Archive Open Error An error occured when opening the backup archive. Cannot continue the operation due to either the backup is corrupted or it is used by another process, for example the backup has been mounted on a disk." The verification of the backup was good, so the file should not be corrupted. I had no other process using the image file. I ran a repair and had the same result so I removed TI 11 from my machine. What is causing the error and how can it be fixed?
