When i run flexsim simulation it (python script) opens and runs without any problems, but if i zip the filder with every file needed to run the script when someone on other pc runs simulation it crashes instantly without any errors. One time when it happend we checked Event Viewer and there was an error in some dll files, but everytime flexsim run this python script it says that crash is caused by different dll file.<BR />what can be the reason this happens. My thinking is that if i zip entire folder with flexsim simulation and python script it should work - the script run from visual studio code works fine.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="filippgawel_0-1777554262650.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1637076i323DFED56CB6EB01/image-size/medium?v=v2&amp;px=400" role="button" title="filippgawel_0-1777554262650.png" alt="filippgawel_0-1777554262650.png" /></span></P><P> </P><P>&nbsp;</P> Thu, 30 Apr 2026 13:07:27 GMT filippgawel 2026-04-30T13:07:27Z https://forums.autodesk.com/t5/flexsim-forum/user-command-python-script-run-from-flexsim-on-other-pc-crashes/m-p/14111988#M100907 <P>Hello<BR />i created a python script that i run from flexsim with two arguments, both of them are excel files, first is an input and another one is a sheet for output.
