I've just tried to install the iPrint client, and it fails with the
following error message:
Failed to install C:\PROGRA~1\MOZILL~1\plugins\npnipp.dll

The system cannot find the path specified.

Error Code: 00000003
MyMoveFile - CopyFile failed 3

The workstation in question has both Mozilla Firefox and Mozilla
Thunderbird, and I think that this is what is causing the problems.

Is there a way to manually install the needed files, or a workaround that
anybody knows about?
