JChem causes crashes

JChem for Office is causing Word and PowerPoint to crash on exiting.

I have looked up the source of the problem, and it pinpoints to PenIMC.dll, which is related to tablet and touch screen devices. I tried to update the .NET framework multi-targeting pack to 4.5.2, but it still crashes with the exact same error.

I have attached the error reports.

Please help me find a solution to this problem.

Please, let us know, with which version of JChem for Office did you experience this issue and what is the exact environment where you installed: windows 7, 8 or 8.1?

Thank you,

Hi Anran,


do you have tablet or dekstop machine?

If you disable JChem plugin does the problem disappear immediately?

I am installing it on the very first Microsoft Surface.

After I disable the plugin, the crashing problem disappears after closing and restarting all Office applications.
