"Help" button does not direct to the user manuals

[activerail]

When I click on the Help Button in the TransDEM program I get a error message: "C:\Program Files(86)\Ziegler-Tools\Dokumentation\TransDEM_engl.pdf" not found. Double (and even triple) checking the file path and it is the same as the error message. What can I do to bring up the two user manuals without going to the file folder and click on them there?

I have to admit I have no idea.

The mechanism has not changed for version 2.3. I have tested the installation package on several machines, XP, Vista and Win 7, both 32 and 64 bit and no problems on those.
