Can't open/convert office files in PDF Architect 7

Hi Guys,

We have a problem with multiple installations of PDF Architect 7 Terminal Server edition. All the users on the server can not convert or open office files using pdf architect 7. If we try with a .txt file it works without any problems but if its a Word or Excel file it gives the following error:

"An error occurred: Failed to open a document"

Does anyone know how we can fix this? This is after reinstalling PDF Architect 7 with all modules and components enabled. We got the standard package using a key.
