i have succesfully added convert and print task on my machine and they were working fine untill this morning when tasks started failing.
error = failed to start solidworks
error message = e_fail "an unspesified error occured"
1.Is this because i have both 2010 and 2011 of SW installed on my machines(but this was workin well till now).
2.Task is initiated and performed on same machine.
3.I have also tested with and without EnterprisePDM add in in SW(on other comp) no issues.
Since the tasks worked before (unless you recently updated SolidWorks or somthing) - maybe you need to define which SolidWorks version the task should use. Open the task, output file details, advanced scripting options and select the SW version in the droplist next to "SolidWorks version to use"
EPDM 2010 has not been verified with SW 2011.
