Yes, exactly. I had one Win7 computer that installed fine. Two, however, will not let me install. I will check the user rights before proceeding.
When I install the program it only allows me to select mapped drives. They are already mapped and I can see everything in them (even delete if I so choose.)
Also, make sure that the mapped drives are the same for those 2 computers as the other one. Depending on how the drives are mapped, you can have drive M: going to the right place on one PC, but another user will have M: going to a different share.
If you are just pointing it to a drive letter, make sure that the files the program needs are there. You may either need to change the drive letter in the program setup based on the PC you set it up in, or a better way is to make sure the users all get consistent drive mappings based on their department and use.
