First time I ran the installer, I got the same message as in the video I linked to. (Successfully installed client profile Forge for version Forge 10.13.1230 into launcher and grabbed 17 required libraries)
but then I got a message from windows that said "This program may not have installed correctly"
I chose the "this program installed correctly" option
When I run it now, I get the same message except the number of libraries
("Successfully installed client profile Forge for version Forge 10.13.1230 into launcher and grabbed 0 required libraries")
However, there is no forge profile on my launcher, and forge isn't an option i can select when setting up a profile.
----------------
When I run the exe from command line, I don't get any outputs but it returns before the gui is even loaded.
I suspect what's happening is that the exe just extracts the jarfile, runs the jarfile in the background, and exits... in this case I wouldn't see any outputs regardless of what's happening.
If forge is in fact installed, I can't see any evidence of that being the case, and I can't run any mods.
-------------------------------
EDIT: Turn this into a bug report I think. I found the issue... it turns out that since I'm not using an administrator account, the installer was defaulting to the administrator's %appdata% rather than the user's. I haven't ran minecraft from the admin account yet, but I presume what happened was that forge was installed for that user instead.
I manually changed the address to point to the correct user on this computer and it works now.
