Well, I’m not sure what you are doing or trying to do.
Please refer to Chris here:
Also note that latest honeybee legacy will continue to work out of the box with OpenStudio 2.9.1 so we might recommend using that unless there’s specific feature in OpenStudio 3.0 that you would like to make use of.
So if you are using Legacy you should stay with an older version of OpenStudio (2.9.1), or use the latest LBT 1.x version to have access to 3.0.1, if you need 3.1, then right now you need to use the development version.
Given that you are fairly new to the forum (I don’t know your experience with LBT or energy modelling), I recommend you stick to the “base” installations to get familiar with the ecosystem and not trying to match the Legacy plugins with the latest and greatest OpenStudio, but I might be wrong here.
In short:
LB 0.0.69 and HB 0.0.66 → OpenStudio 2.9.1 (this is what you were trying to get started with)
LBT 1.1 → OpenStudio 3.0.1
LBT [development version] → OpenStudio 3.1
You also have problems with Therm, don’t install the latest 7.7, it won’t work (7.6 is the one you should use). But you also have problems with Radiance and Daysim too, so either you have permission issues (did you unblock the components before installing?), or something else, I’m out of ideas here.
