When installing ndLink on a 64-bit system, you may see this error:
To resolve this, run the NDLink install.
Open the following files using a text editor (you may need to run it as an Administrator):
C:\Program Files (x86)\NetDocuments\ndLink\ndLink.exe.config
C:\Program Files (x86)\NetDocuments\ndLink\ndLService.exe.config
Each of these files has 1 line that refers to the Program Files filepath. That line needs to be updated to reference Program Files (x86) instead of Program Files.
