[ALPS-users] Error message in RunDMFT module: DMFT-04 Vistrails tutorial on ALPS

Dear ALPS users,

I am trying to execute the DMFT-Tutorial-04 (and DMFT-Tutorial-05) vistrails file, downloaded from the ALPS webpage, using ALPS 2.2b1 on Windows. However while running the workflow the below error is encountered at the RunDMFT module:

=================================================== Cached: No Completed: No Error: Execution failed

Annotations: errorTrace: Traceback (most recent call last): File "vistrails\run.py", line 47, in <module> userpackages_dir = os.environ['VISTRAILS_USERPACKAGES_DIR'] File "C:\Program Files\VisTrails\Python27\lib\os.py", line 423, in __getitem__ return self.data[key.upper()] KeyError: 'VISTRAILS_USERPACKAGES_DIR' ====================================================

From the message it looks like there's a problem with my environment

settings of Vistrails, but other vistrails files downloaded from the ALPS webpage work fine. Any ideas on what might I might be doing wrong are appreciated.

Thanks, Vipin
