Detect which Framework is installed (including language)

[Thomas Jespersen]

How do I detect which language the .NET framework is installed with?

I want to know this because we have an error related to .NET 1.0, which is
corrected in SP3 of the framework. I want to detect if the client is running
..NET 1.0 without SP and offer a download link. But if my client is running
..NET 1.0 US it should be a link to the US SP3 and if the client is running
..NET 1.0 Danish, then the link should point to the Danish SP.

I know I could tell them to run Windows update, but I want to use our own
high-speed servers.

Method 1:

1.) Under HKLM\SOFTWARE\Microsoft\.NETFramework\policy\ check to see if the
version you want is installed (for example, look for the v1.1 folder and
4322 for the version number to detect the released version of V1.1)

2.) Under HKLM\Software\Microsoft\.NETFramework\InstallRoot get the path
where the Framework is installed. Create a directory string by concatenating
the install root and the version under policy. E.g.
"C:\WINDOWS\Microsoft.NET\Framework\" + "v1.1" + "." + "4322"

3.) Look at the directory, if mscorlib.dll (or another critical .dll to the
..NET framework is there) the runtime is installed.



Method 2:

There's a caveat to this method in that the shim gets left behind when we
uninstall if there is more than one version of the CLR on the machine, but
it still can be useful depending on what version you're looking for:

LoadLibrary("mscoree.dll"); - if this fails then there's no runtime
installed

GetProcAddress("CorBindToRuntime"); - if this fails there's no runtime
installed

CorBindToRuntime("GetRequestedRuntimeInfo");

GetRequestedRuntimeInfo(xxxx); where xxxx is the build number.

Hello

Hmm. Maybe I didn't express my self clear.

I know for a fact that my clients has .NET framework (otherwise they would
not be able to run my program).

What I want to check, is whether they have the latest SP (I know how to do
that), and if they don't I want to detect whether they should be offered the
Danish or US Service Pack.

So my question is: How do I detect which language (US or Danish) of the .NET
framework is installed.
