I am pretty new to Houdini but was playing with the Tree Generator in R19 before updating to R19.5 and now the Tree Gnerator is missing from both versions. I installed labs using the Houdini Launcher but the Tree Generator still doesn't show up now in either 19.5 or 19, and it seems like other labs are missing as well. How do I fix this? I tried installing both the R19 Labs and the R19.5 labs but no luck. Any ideas?

I have this, and it is on a fresh install machine
if those are what you are looking for, something is funky on your side

I'm on Windows 10, and I have it.

What's your operating system?

How about trying to install without using Houdini Launcher?
