this should probably be in a new thread, but i cannot move it .
first off, under file or the app in menubar there should be a preferences option, select it. Does the python location point to the python exe you installed?
if it does, there are a number of things we will need to do to track this down:
1) look in your Documents/EE-UQ folder. there is a file debug.log. the end of the file may show errors related to why failing.
2) in the LocalWorkdir/tmp.SimCenter/templatedir dir there should be at least a dakota.out file (this is the input file for the python app)
3) look in LocalWorkDir/tmp.SimCenter, there is a file log.txt if python was found (look in it for obvious errors, i.e. a python module not loaded)
4) if the UQ engine started there should be a number of workdir.X folders in tmp.SimCenter (if they exist the analysis is failing)
can you post the debug.log, dakota.in, log.txt and a worflow.X compressed folder as attachments in your next post.
thanks and sorry.
