@oraniko When a snapin or snapinpack runs forever, usually this means it’s waiting for input. And snapins are not allowed to receive input, nor interact with the end-user in any way.
So, to troubleshoot, Step back and start without even involving fog. Unzip all these files to somewhere - open an elevated command prompt, cd to the directory and run setup.exe
and see what happens. If it doesn’t “just go” without asking for any input whatsoever - then it needs work. Once you have it “just going” without any help, take that work and those commands and make a snapin or snapinpack with them. The links I posted below are full of resources & ideas.
