1. Look for the program bdeadmin.exe and launch it (this program is most likely in the folder C:\Program Files\Borland\Common Files\BDE\).
2. Select the Configuration tab and then the Drivers/Native/PARADOX tree node, as shown below.

3. Make sure that the LANGDRIVER is set with the value Paradox 'intl'.
4. Make sure that the NET DIR points to the QppShare folder (usually Q:\Qppshare). Do not change any of the other settings.
5. Select the Configuration tab and then the System/Init tree node, as shown below.

6. Make sure that the LANGDRIVER used for is set with the value Paradox 'intl'.
7. Make sure that the value of LOCAL SHARE is set to TRUE (do not change any of the other settings) :
