Define a valid Windows environmental variable for the temp variable.

To check if the variables are present:
 

1. Click Start, Run, type sysdm.cpl, and click OK.
2. Click the Advanced tab.
3. Click Environment Variables.
4. Review the System variables. Confirm that a variable is defined for both TEMP and TMP. Confirm the variable points to a valid path with no spaces for a folder that currently exists on the system.

If one or more of the variables are present but point to an invalid path, do the following:

1. Select the variable from the System variables list and click Edit.
2. Enter a valid path in the Variable value field and click OK.
3. Click OK.
4. Click OK to close System Properties.
5. Restart the system.
   NOTE: A restart is needed for any change to Windows environmental variables to be applied. 

1. Click New under the System variables list.
2. Enter TEMP in the Variable name field if the TEMP variable is missing or TMP if the TMP variable is missing.
3. Enter a valid path with no spaces in the Variable value field and click OK.
   NOTE: The Windows default path is C:\Windows\Temp.
    
4. Repeat steps 2–3 for the other variable if both variables were missing.
5. Click OK.
6. Click OK to close System Properties.
7. Restart the system.
   NOTE: A restart is needed for any change to Windows environmental variables to be applied.
