Rhinoceros 4 install problems

The installer extracts and then nothing happens
Tried to restart, same result

This is on windows server 2012 r2
Might the os be the problem?

You might want to reboot to clear any running but invisible installers.


Thank you
but now that I have installed rhinoceros, i have problems aplying flamingo 2.0
