I did an application in vb5 (enterprise edition with service pack 3) using a database in access 97. These two were shared by some users in a TCP/IP LAN. Recently some of these users changed from access 97 to access 2000. So, I had to upgrade DAO 3.51 to DAO 3.6 . Now a problem arises: all the forms that use dbgrids don't work and give a run-time error 713 (Class not registered). Note that I cannot convert my database to access 2000 because some of these users still have access 97. Can anyone help solve this run-time error?
