iLogic Rule Compile Errors: External component has thrown an exception.

[duy.nguyenJYSF4]

I just got my Inventor upgraded from 2018 Pro to 2021 Pro version, and this error kept pop up here and there to all of my ilogic codes at the same time randomly. My iLogic codes work very well on 2018 version, never get any error before, and just started happening on 2021. I don't know exactly what is going on, but to get away with it, I just close and reopen Inventor, and it seems  running normally after that, but it's getting super annoying now to close inventor during a project.

See below for details.

System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.

Hello

Is there a rule that loads an external dll file and is this file missing?

[duy.nguyenJYSF4]

No, none of them load a .dll or missing file. Some of them have very simple cmd copy page of drawing, or flipping the page, etc.

@duy.nguyenJYSF4 , please try the workaround described at the bottom of this page. Although the problem described there is different, there is a chance that the same workaround (setting the iLogicRuleFolderForVS environment variable to 0) will fix it.

Another thing to look at:
In the Tools > Options > iLogic Configuration dialog, there is a Security Options button. When you click on that, it will bring up a Security dialog. In that dialog, there is an option to "Inspect rules for malicious code". Do you have that option enabled?

My drawings Rules would not work since new years. This workaround on that page worked for me.
thanks
