Help me with java and windows 10?

I have already bought a minecraft key -.-

at first the technic launcher stopped working

I have jdk 14 and java setup 8 update 251

but somehow it doesn't work -.- i'm desperate normally an installation like this is not that difficult

the technic launcher spins around

The best thing to do is get Java 8 for Mc

The trick was to go down the list from 14 to 8 which yesterday yesterday unfortunately did not tell me ^^ but it all works and yes I have the version
