When installing software via Windows Remote Desktop, a separate 'temporary folder' for each user is created by default (for example: Temp\5, with 5 denoting the user No5).
As such, if the software requires files to be stored in the default Temp windows folder, the installation procedure will fail.
The setup procedure must be run physically logging in to the Server using a domain or by a local user that has administrative rights.
This way the setup will find the 'normal' temp folder.
If there are difficulties with the above solution, the following procedure must be followed:
a. With a remote user that has admin rights on the server, press the windows start button and the 'S' key from the keyboard simultaneously.
b. Type the following line:
Local Group Policy
and press enter
c. Locate the setting 'Do not use temporary folders per session' by expanding the tree nodes on the left side of the 'Local Group Policy Editor' dialog:
Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Temporary folders
d. Double click it and in the appearing dialog click on 'Enabled' and press the Ok button.
With this setting, the temp folder will be the same for the physically logged user 'administrator' and the remote desktop user that has logged in using the 'administrator' user credentials.
The server may have to restarted in order for this setting to be applied by Windows.
