You get runtime error 3051, "Cannot locate database, or database in use by someone else", when you try to print forms. This is not happening on all PC's.

How to Fix

This error most likely happens due to copying your forms file from a CD.  By default, CDs are "Read Only" and when you copy from the CD, the read only attribute carries over to your system.

To fix, simply right click on the ALPSFORM.MDB file or FOFORM.MDB file and select properties. Uncheck the READ ONLY box.
