Since upgrading to version 3.6, I am getting an "access violation error at address 004065F8 in module TDM.exe read of address 0D0A0D06"
Problem with user packages or system packages (files *.txg).
1. Uninstall TDM
2. Rename
C:\Documents and Settings\{user name}\My Documents\Toad Data Modeler folder to C:\Documents and Settings\{user name}\My Documents\Toad Data Modeler_old
and
'C:\Program Files\Quest Software\Toad Data Modeler X.x' folder to 'C:\Program Files\Quest Software\Toad Data Modeler X.x_old'
3. Reinstall TDM
RESOLUTION 3
Make sure the version of Toad Data Modeler is a supported version.This can be seen in the "Product Life Cycle" tab here
If it is not supported, then download and install the latest version.
The installer for the latest version can be downloaded here and all the documentation (System requirements/installation guide...) here.
