Hi Anuj,
The TestStand installer creates a <TestStand 3.1> subdirectory in
whatever directory you specify during the install. By default, this
specified directory should be
C:\Program Files\National Instruments
The additional TestStand 3.1 directory you are seeing could be a result of the person installing the software specifying
D:\Program Files\National Instruments\TestStand 3.1
in the installation dialog, not realizing the TestStand 3.1
directory would be created by the installer without need of specifying
this.
The best way to ensure that only one directory is being created is to double check that
D:\Program Files\National Instruments is the directory specified during installation. The installer will only create 1 TestStand 3.1 directory.
Hope this helps Anuj, let us know if you have any more questions.
