I have Hero Edition for Windows 7/8/10 and i try to run it on windows 7

Here is what i do:

• starting minecraft dungeons launcher
• click -> ,.login'' (zaloguj się - in my Polish version)
• then in new window -> sign in
• login/password/sign in
• next i click - Let's play!
• and then > Play (in Polish graj)
• and after few seconds of thinking nothing happens

In Windows task menager I can see:

• Dungeons.exe (0 CPU)
• Dungeons-Win64-Shipping.exe (25%CPU)
• Minecraftdungeonslauncher.exe *32 - 3 processes () CPU

What did i try:

• reset
• add admin privileges for launcher
• turning off antivirus (avast)
• reinstall
• repair
• run on other PC - (worked but it had windows 10)
• borrowed hard disc with windows 10 from other pc and try to run it on this PC, (yup, also worked so no hardware issues - it's problem with windows)

That's all
