Question from one of my non-technical colleagues; I'm trying to use JSim 2011 January release but for some reason Symantec Antivrus is deleting one of the .dll library that JSim 2011 release needs to use. In another words, whenever I try to run JSim, Symantec does not allow me to do that because it thinks odesolver.dll is a trojan. Here is the answer that solves his problem; First try to disable active protection in Symantec Antivirus from the settings when you run JSim. If it runs successfully, you should be able to add exception for the executable of JSim into Symantec Antivirus as JSim is a safe program.

Yesterday I installed Symantec Endpoint Protection to my Windows 7 Professional. Nonetheless, the "Confidence Online Utility Driver" does not work on Windows 7. On the Symantec site it is said that this problem will be solved in a couple of week. Then, we are watching them... FYI http://www.symantec.com/connect/forums/sep-driver-crashing-windows-7-x64 UPDATE: Here how I solved it; just uninstalled the antivirus software and then reinstalled it. Works fine right now.
