Technical Support: Removing Corel's BDE Installation

Users who have Corel WordPerfect Suite 8 installed may encounter messages such as "merging the configuration file failed" and "version interface mismatch" while installing and running Trooper. In a nutshell, Corel's installation of the Borland Database Engine (BDE) is incorrect, and attempts to upgrade their version result in these errors. Unfortunately the only solution is to manually remove all folders containing the BDE, then manually remove all registry entries for the BDE, reboot, then reinstall Trooper.

This page provides more detailed instructions on how to remove your damaged copy of the BDE. If you are not familiar with REGEDIT, Microsoft's registry database editor, be very careful with it, as deleting the wrong information can cause problems with your PC. Run REGEDIT using the Start>Run... dialog (type in "regedit" and click "OK"). If you have ANY questions about using RegEdit please don't hesitate to contact technical support for assistance.

We have identified the registry keys below on our systems; your version of the BDE engine may differ slightly if it is an earlier version.

When you run REGEDIT, a double-pane screen will appear, and you will see 6 folders on the left. Click the plus sign next to them to show the subfolders underneath each. For example, expand HKEY_CLASSES_ROOT so you can scroll all the way down to the folder called Borland.Database_Engine.4 (fortunately, they're in alphabetical order). Delete this folder.

Next, open the HKEY_LOCAL_MACHINE main folder, and under it the Software and Borland folders. In the Borland folder, click once on the Database Engine key. On the right side, the DLLPATH item shows where the BDE is installed on your system (normally this is C:\program files\common files\borland shared\BDE but it may be different). Make a note of that location. Then, delete the BLW32 and Database Engine folders.

Now browse down to the folder:


On the right is a long list of file names. Scroll down to find all the BDE files, such as

C:\Program Files\Common Files\Borland Shared\BDE\BANTAM.DLL

...and delete that line on the right. There are probably about 30 of them to delete.

We're almost scroll the left pane of REGEDIT all the way to the top, and click on the "My Computer" icon. Click on the Edit>Find... menu choice, and seach for IDAPI. If you find it, it will show up under a folder with a gobbledegook name, something like:


Delete that whole folder (the one with the funny name). Next repeat this step but search for Borland Database Engine. Now you can close REGEDIT.

OK, one last thing; we need to remove the BDE directory on your hard drive. Remember the note indicating where DLLPATH was pointing? We need to delete that folder. Open "My Computer" on your desktop, then follow down the path you wrote down ("Program Files", "Common Files", etc.). When you open the "Borland Shared" folder you will see a "BDE" folder. Delete it.

Whew! Easy, huh? Blame Corel for not following the rules when they installed their version of the BDE. If you're still with us, I appreciate your patience. I'm sure you'll find Trooper worth the trouble! Now, you just need to reboot and reinstall Trooper to be on your way.
