Why is MDAC 2.8 RTM and Jet 4 SP7 included in the THUM installation program?
The THUM uses Microsoft MDAC/ADO/JET components to save data to an Access table. The Data Conversion Utility also uses ADO/Jet. We have found that many software installs attempt to install different versions of MDAC. This can lead to mismatched dll files, which may cause the THUM not to function properly. In an attempt to make the THUM installation as easy as possible, we have included the newest versions of MDAC and Jet in the install. This should update any mismatched files and allow all MDAC/Jet dependent applications to run correctly. If for some reason, you do not want to update the MDAC/Jet versions on your computer, e-mail support@practicaldesigngroup.com and we can send you an install without MDAC and Jet updates.
