I am developing Delphi 7 application, which is operating with Access Database (MDB format). It works fine on my PC, and some other PCs as well. But on some machines application gives error when trying to access database sometimes, saying something like "Unkown database format (mdb)". Additionally I noticed one thing: When you open that database in Ms Access using Office, it is opened in "read-only" mode for some reason. Can anybody help? What could be the reason for the problem?
I think your most likely problem is to do with MDAC, use the registry to check what version is on each machine and see if there is a differnce between the ones that work and the ones that dont.
