Hi! I'm learning sword's Sobble route, but the IV calculator won't open. I've tried ina windows clean os, updating java and making sure that there is not an older version. It just wont work. Any ideas or somebody already figured out how to make it work or if it's a common issue?

Figured out. For someone that has a similar problem / reminder. I install Java SE Development Kit (JDK) for my work as a programmer, uninstalled it and ran the calc by powershell and it worked.

So, it wont work with SDK installed
