When attempting to save changes in the DocuWare Administration Tool, you receive the following error:

"cannot save changes, please see logging for details"

Additionally, when trying to add an additional Organization, you receive the error: 

"Object Reference Not Set to an Instance of an Object"

This is due to a mismatch between settings dlls in the Admin Tool folder and the Web\Settings folder. To fix this issue do the following:

  1. Please navigate to "C:\Program Files\DocuWare\Web\Settings\bin" and copy these 4 dlls selected in the picture below.

  2. Then go to C:\Program Files (x86)\DocuWare\Admin Tool Online and paste them there.

Restart your DocuWare Administration Tool.
Saving changes or adding an additional organization should now work without error.
