How to delete Registry Key SAP_DBTech


I fatally deleted too many files of my Sneak-Preview (I didn't want to do so, so let's don't discuss why or how this could happen) so that now nothing works anymore.

The attempt to reinstall stops at the same point like the attempt to delete it via UNINSTSAP.BAT:

"MDB-07057 The system is inconsistent. Registry or SAP_DBTech information is available, but software is not complete."

I tried to delete the specific Registry-Entries, but the System didn't let me to do so.

Is there anybody having an Idea how to tell the Installation to ignore the Entries in the Registry or how to delete the Entries in the Registry?

You can delete the registry entry by.....

Start Menu --> Run, type regedit, hit enter. In the tree structure open HKEY_LOCAL_MACHINE, SOFTWARE, SAP. Delete the folder for the corresponding sneak preview engine(J2E or NSP). Also delete folde SAP DBTEch.

Now, from the c:\ drive. Delete the folder c:\usr and c:\sapdb. You may have an issue deleting these folders because they may be in use. Make sure that you reboot your system, do not start the engine, then delete these folders. Still having problems, disable the service if needed.

Once all this is cleaned up, you should be able to reinstall.
