Hi Brent,
I have not tried this on Capella 5.0 but:
- on the Req VP, you should probably uncheck one of the features you are trying to install, The error you get is related to the fact that you are trying to install a feature related to the compatibility of this add-on with Team for Capella (https://www.obeosoft.com/en/team-for-capella) so you do not need to install it if you’re not using Team for Capella
- Not sure about the other one but it looks like you are trying to install some tests. So maybe again there is a feature that you may uncheck as you do not need the test for this one. But honestly, I am not sure. Also make sure you are installing this version: Addon System to Subsystem Transition v1.5.0 has been released
Let me know if this helps, if not I will try to find some time to test this.
All the best,
