Toad Data Modeler (TDM) gets the error: "Error accessing the OLE registry".
The "Error accessing the OLE registry" error is thrown when other applications has a particular system COM object registered, and the application you are trying to start needs the COM object to have registered for itself. This happens when running two TDM installations side-by-side, e.g. has TDM 4.3 and 5.0 is installed; 5.0 is started without any issues, but when trying to start 4.3, the said error is received.
Start the version throwing the error with Administrator rights in any way possible, e.g. right-click the TDM Shortcut or TDM.exe and select "Run as Administrator".
You can also set TDM to always start as administrator with the following steps:
Right-click the TDM Shortcut or TDM.exe | Properties | Compatibility tab | under 'Privilege Level' section | check-mark "Run this program as an administrator". Next, below that, click the "Change settings for all users" button to set this option for all users.
