After Select Help-->About, Origin is stunk. Reopen Origin and I simply used some function of the software ,It seems that it is OK. I installed pro trial version.
Maybe you ran Help About immediately after starting Origin? The help about dialog is based on Origin C which took some time to finish initializting after start up.
So can you just wait a second after running the software before choosing Help About?
I waited a long time, and it's the same to start About dialog. And I found that by delete a parameter DLG_HIDDEN in dwOptions, I can open the about window, but there is no text message in window.
