The cause

Windows includes the two variables TEMP and TMP for the temporary directory. Both variables point in general to the same directory. If, for any reason, this should not be the case, the product installation leads to an error message.

Background information:
During the installation of Avira Exchange Security a PowerShell script will be invoked that saves the result in the file %TEMP%\E2K7.tmp. Subsequently, a read access to the file E2K7.tmp will take place via the variable TMP. If the two variables point to different directories, the file E2K7.tmp cannot be retrieved. Therefore, the installation will be canceled with the current error message.

Validation of the paths

Verify if the paths of the variables TEMP and TMP coincide and point to the same directory. Perform this task by using the CMD console or the PowerShell.

Command for the CMD console:

Command for the PowerShell:

Solution

If the variables TEMP and TMP are referenced as in this example to different directories, then the paths need to be adapted to point to the same directory. The adaption of the paths must be applied in the system properties.

Start → Control Panel → System → Advanced system settings → tab “Advanced” → Environment Variables… → Edit…

Once both variables point to the same directory, the installation of Avira Exchange Security can be performed.
