@Elrood:
According to that uninstall tool from Oracle I do only have one Version of Java installed Java 8 V 161 and it cannot be uninstalled… so probably that installation is broken somehow…
But i installed now Java 8 V 171 64 bit and now it seems to work fine.
thanks
Ah ok. it looks like you have once downloaded and installed a TripleA-version that came with a bundled Java.
That is why the Java tool cannot find that old installation.
Your old and outdated Java is here: c:\program files\common files\i4j_jres\1.8.0_66\
In case there is no respective entry in the “Systemsteuerung - Programme…” you can manually delete the folder “1.8.0_66” including its subfolders.
Glad that it works now. :-)
