Unable to open vensimdp.ini error on application open

[RobbieOrvis]

Hello,

My colleagues and I have recently been running into a "Stop from Vensim" warning on application open in which Vensim states it is unable to open the vensimdp.ini file for read/record initialization information. This appears to be happening on DSS 9.3.5.

When this warning appears, Vensim will always default to opening the model in sketch format.

Other colleagues have tried completely uninstalling and reinstalling but are getting the same error.

I cannot pinpoint when or why this warning started appearing on my machine.

I attached a screenshot of the warning.

Are you still using the old GUI?

[RobbieOrvis]

Yes, we've been using the old GUI after running into some issues with the new one.

This is probably the reason. It's becoming increasingly difficult to keep the old GUI operating (it doesn't work at all on the latest version of MacOS).

What issues are you experiencing with the new GUI?

[RobbieOrvis]

I will switch back to the new GUI and log bugs going forward instead of staying on the old GUI. It's been a few months since I switched back so I don't recall exactly.
