Tech Tip: AutoCAD Fatal Error

When installing AutoCAD ADT 2006 recently I came upon this error when starting CAD to configure settings:

AutoCAD Error Aborting.

FATAL Error: Unhandled e0434f4dh Exception at 7c59bc81h

This happened after installing Express Tools for ADT. The fix I came up with was to install the latest ADT Service Pack...

Tech Tip: InstallShield Error 1607 under Windows 2000

Every once and a while, we come up against errors which shouldn't happen, but do. One such incident started happening to me lately while loading machines with software in work...

Every time I tried to install a certain application (which worked fine the first couple of hundred times I installed it) I would get InstallShield Error 1607. Searching Google gave me a couple of fixes but none worked. Eventually, I narrowed the cause down to one thing: Windows Installer!

To fix this error, go to Control Panel, then Add/Remove Programs. Uninstall Windows Installer 3.1 (KB893803). This will give you a dialog similar to the following:



Click 'Yes' to this, we will fix this in a moment... Then immediately after the uninstall, go to Windows Update and install any updates available (Windows Installer 3.1 should come up as a required update). Once this intalls, those programs will work fully again (afaik, you can run them but not uninstall them properly until Windows Installer is restored).
