Feature Explorer Error?

[napalmer]

Whenever I try to open up my features in the Explorer this error shows up...

Cannot display view because the following error occurred:

And I can't change my installation architecture with the assistant either. any ideas what happened or how to fix it?

[napalmer]

It also seems to be disabling my ability to customize my Installation Types. The top portion of the Properties in Installation Types (the area where you can select the components to associate with that installer type) doesn't show up. I loaded up a different project and there was no problem, so I must have done something in this project version.... anyone have this happen before?

I haven't seen that specifically. The stack trace points to an Execute Process action; as a test, could you remove that from a copy of your project and try to open this copy?

[napalmer]

I found the execute process that was causing problems and deleted it (thank you for the information). Just to test it though, I remade that same execute process and it still works fine which seems kind of odd, but thanks again for the help.
