Just installed Windows 10 and Eclipse no more starts

Question

I just upgraded from Windows 8 to Windows 10 (both 64-bit) and my previous Eclipse Juno with ADT-plugin for Android development is no longer starting.

All I can see

Answer 1

I had my Java path set correctly in eclipse.ini but forgot to check "bitness" of eclipse and JVM. These have to pair (32 bit or 64 both) otherwise eclipse fails to start without error or message.

It is a foolish error but not so obvious when upgrading, so maybe this saves someone else few minutes or more...
