Hi Arunkumar.K,
for exactly this type of questions SiteScope is shipped with a wide set of manuals.
Check the Deployment Guide, Chapter 6: Before You Install SiteScope, System Requirements
..
Server System Requirements for Windows
32-bit
- *Microsoft Windows 2003 SP2 Standard/Enterprise Edition
- *Microsoft Windows Server 2003 R2 SP2 Enterprise Edition
- Microsoft Windows Server 2008 SP1, SP2 Standard/Enterprise Edition
64-bit
- *Microsoft Windows Server 2003 SP2 Standard/Enterprise Edition
- *Microsoft Windows Server 2003 R2 SP2 Enterprise Edition
- Microsoft Windows Server 2008 SP1, SP2 Standard/Enterprise Edition
- Microsoft Windows Server 2008 R2 SP1 Standard/Enterprise/Datacenter Edition
So obviosuly SiteScope 11.22 is NOT supported on Windows 2012,
no matter what JRE version or browser type and version you are using.
You should install SiteScope 11.30 or even 11.32 instead, this version is supported on Windows 2012:
Server System Requirements for Windows
