Hey there !
I think Versionner might have some problems…
I don’t know if this happens to other users, but every time I’ve used Versionner to update to last version (and checking compatibility matrix if some installs have to be done again), the run recipe simply stops working. (Windows machines, LB version 1.1.1). The widow shell pops up, all black, then closes after a seconds. No errors from ladybug, but not results as well 
I’ve used the “LB sync Grasshopper file” and manually replaced the components that were not changed, doesn’t work.
I’ve tried replace all components manually, doesn’t work.
I’ve restarted computer, doesn’t work.
I’ve uninstalled and reinstalled Radiance + restart, doesn’t work.
It is not a problem with my file either, all of this happens on sample file “daylight_factor” too.
Solution : Manually uninstall everything (all C/: folders related to ladybug) and install from scratch.
Any idea what could cause this and how to fix it?
Thank you very much !
Cheers
