Unity opens 20+ windows, when importing asset

Question

So, I'm trying to import the "Toms Terrain Tools" into a project. And when I do it gives me a loader that says something like " Decompressing asset"

After it's been doing that for 5 minutes, it opens ALOT of random windows of stuff I have on my computer. Does anyone know what it is, and have a solution to it?

This is still a bug even with Unity 5. It's been happening forever.

I've been having the same problem with a 160 MB asset I got from the asset store (Cartoon Forest Environment). Unity 5.0.2.f1 Personal. Opens a bunch of different random programs (some of them have weird acting unclosable windows).

It happens during the decompression phase, the 7z.exe bundled with unity will run at 1-3% cpu for 5-7 minutes, the progress bar will not move at all, then suddenly a BUNCH of windows will pop up.

Tried importing asset again, didn't work.. Tried reinstalling unity, didn't work, I just reinstalled windows as well, so had a very clean install (only essentials like chrome, 7zip, vlc) but I still had the problem.

Workaround / fix!

Import project in the asset store. (downloads it)
Let unity crash and reboot (or if there is a way to prevent this by hitting cancel on the decompression, do it)
Start unity and open a project
Go to "C:\Users\username\AppData\Roaming\Unity\Asset Store-5.x" and double click the file, this will decompress and import the asset into the current project

Maybe the project you're trying to import the asset to is just too epic beyond proportion?
