Earlier, I'd decided to change the installation directory of TDS-3. After un-installing it, I rebooted my machine, and noticed that the TDS-3 folder was still alive! It also had a single file (if I recall correctly) named "execprot.dll". Somehow the un-installation had not deleted this file. My subsequent attempts to get rid of it also produced an error message by Windows, stating that it was locked or used by a process! Any ideas as to how to make the un-install completely remove everything related to TDS-3? Thanks.
