How can I find out if .NET 4.02 is installed?

I've asked this question yesterday - it was closed as "exact duplicate" by some people who didn't take the time themselves to read questions / comments carefully! So, another try - maybe it gets the time to receive some working answer before being closed for some pointless reason again.

Microsoft has recently released some "update" for .NET Framework. Unfortunately, I don't know any way to find out which version is installed. Framework-Version stays on 4.0.30319.239.

Thanks for some enlightement ;-)

PS: Setting supportedRuntime in app.config to Version=4.0.2 makes the application tell me at startup that 4.0.2 is not installed (in no time - so there must be some place where the "real" version can be found).

Have a look at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs

If you have installed 4.0.2 then there exist these additional nodes:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.1
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.1,Profile=Client
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2,Profile=Client
