'Error Reading Documents - Class not registered...' when switching between modules

I'm getting the following error: Error Reading Documents - Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) when switching from Estimating to Comparisons.

This error is caused by a corrupt file on your computer. The class not registered error usually stems from faulty DLL (.dll) files.

It looks like ConQuest, has a damaged installation or needs to be registered. Either your IT team can help you to repair it (via Add/Remove Programs from Control Panel) or register it (via Regsvr32.exe).

Another solution would be that before you open your ConQuest application:

  1. Right click on the Desktop icon

  2. Choose Properties

  3. Go to Compatibility tab

  4. Run Compatibility troubleshooter

  5. This way Windows will choose the right settings to make the application compatible.
