MFG/UTIL and QAD UI Installations
Any installation process updates MFG/UTIL. This is especially true when you install the QAD UIs over QAD Standard Edition, or a service pack over the QAD UIs, since MFG/UTIL for both of these is installed into the database server directory. Some MFG/UTIL functions, including conversion routines, are specific to certain versions of MFG/UTIL. As a result, some functions may not work correctly if you overwrite the existing MFG/UTIL version.
To avoid any mismatches, back up your existing MFG/UTIL version. Once you have installed the QAD UI over QAD Standard Edition or a service pack over the QAD UI, back up that version of MFG/UTIL as well. If you need the prior version of MFG/UTIL—for example if you are running a conversion after installing the QAD UI—restore the prior version.
To create a backup, include the following directories:
QADInstallDir
QADInstallDir/xmfgusrc
