I've installed the application and everything works just fine. There were no errors or something related about it.
The version installed on my PC was the latest one and downloaded from the developer's website: http://www.neuber.com/free/svchost-analyzer/
Note: You need Windows 10, 8, 7, Vista, XP, 2003, 2008 (32/64 Bit) and for XP, Service Pack 3 is necessary or you'll receive that error above.
