There is one specific computer in which only Toucan 3.0.0 works. I just click enter and nothing happens. When I open the internal app\Toucan\toucan.exe directly, I get:

I've tried renaming folders and re-installing but nothing helped. Only re-installing 3.0.0 worked. I bet it's something regarding dependencies which didn't exist in 3.0.0.
Please make it as independent as 3.0.0.
