1.2.1 Command Failure for External Command

I got this command failure for external command for the first time from release 1.2.1. This never happened to me before with previous dynamo releases. Any ideas?

please post this to the GitHub issues page.

This seems to be similar to Dynamo crashing at Startup, there might be some addin causing conflict.

@Hex_Ceballos, You might want to uninstall FINALCADCOLORIZER, if you have this installed. This aad-in has been causing issues during startup.

@Sharad_Jaiswal I had colorizer installed. I uninstalled colorizer and dynamo, reinstalled dynamo. It seem like that was the problem. Thanks!
