I am attempting to move roundup issue tracker to a new server. I have
installed python 2.7.14 (previosly the version was 2.7.6) and I am
recieveing the following error when attempting to start the roundup
windows service:

The instance's SvcRun() method failed 
Traceback (most recent call last):

    from roundup.anypy.sets_ import set
ImportError: No module named sets_ 
%2: %3

If I remove the nosyreaction.* files from the detectors directory in the
tracker home, the service starts as expected.
