Yes, I got it directly from Piriform web site, latest version. Those are 2 brand new servers and Ccleaner never run on either one.
I did shut down all AV soft and disconnected server from network, just in case.
No changes in Ccleaner behavior.
I removed installation via uninstall -> restarted server and manually cleaned registry from any and all remains of Ccleaner first install - just in case.
Re-booted and install again.
No changes!
Could it be some kind of compatibility issue with 64 bit OS? But then again, same behavior apply for 32 bit 2003 server...
