I installed the portable toucan in my computer's hard drive. When i open toucan, a command prompt like windows opens but it closes after a second. Then the splash screen of toucan and Portableapss appear. I tried running toucan on my flash drive and it doesn't show up any of those black windows.
like you are running the app itself and not the launcher which takes care of the command prompt as there is no distinction in the code between the ubs drive and the hard disk
