OpenToonz V1.5 Won't Open

[Puggytatoes]

Hi, I wanted to try out the new version of Opentoonz so I uninstalled it and downloaded version 1.5 from the website. Initially, it has the start-up small green square menu (with Creating main window ... loading style sheet ... and then starting main window) and usually the program opens up immediately after this point, but the small menu closes and the actual application never opens up. 

I tried uninstalling the program, reinstalling it, and restarting my laptop several times but it still has the same issues. I've just been uninstalling Opentoonz's previous versions through the Control Panel, is there something else I should be doing? Let me know if you need any information about the situation and I'll do my best to provide it. Thank you!

install it again, and use a software to make a clean uninstall (deleting targeted appdata and registry)

After uninstalling, delete your C:\OpenToonz Stuff folder, then install. That should help.

It worked! :) I had to delete the C:\OpenToonz Stuff folder as well as the components related to OpenToonz in Program Files before reinstalling. If anyone else is having this issue, make sure when deleting to keep your project files in the recycling bin or a USB drive (and to put your projects back in afterwards). Thank you so much for your help (and thank you for all your great tutorials)!
