Running Update Generator 'generates TEMP'error

When starting Update Generator version 9.1 I get the following error:
The %TEMP% path contains a trailing backslash ('\')
All Environment Variables for TEMP and TMP (in this case Win7) point to a temp directory on F: > F:\TEMP
Does anyone know a solution?
