Multiple .NET on same machine

[Guest]

Hi,
I attempted to load .NET 2.0 on my meain development machine, but it refused
to load as I already have 1.1 installed. The error message is as per
Microsofts installation notes
(http://www.microsoft.com/downloads/...95-717C-4EF7-817B-BDEFD6947019&displaylang=en)

How can I install different .NET versions on the same machine?

Thanks
Tony

As I read it, you can't install 2 different versions with different national
languages (US, UK, or French, for example). I had no problem installing 1.0
and 1.1 (both US) on the same machine; in fact, my understanding was that
that is normal practice, so that each .NET program will use the one it was
compiled for. Haven't tried 2.0 yet.

Hi Tony,

As Michael said you cannot have to different .Net languages and since 2.0 at the moment exists only in English I suspect you have a non-english version already installed.

You can try to uninstall the .Net 1.1 you have and install the english version of 1.1. You should then be able to install 2.0 as well.

You can get the English version of .Net 1.1 here

Thanx to both for your replies, and they make sense. The only problem is, I
believe I installed the english version (being one those myself in the US),
but how can I establish which language version I have actually installed.
I looked to the reg, but only found the following keys under ASP.NET:
LastInstallTime and RootVer: 1.1.4322.0
The subkeys show the following keys:
1.1.4322.0: DefaultDoc;DllFullPath;Mimemap;Path;SupportedExts
MacineAccounts: ASP.NET

None of which (apparently) indicates the language version.
The only other regkey (of any significance) is the
..NETFramework/PendingUpdates/v1.1.4322/NI and NID, which both point to file
ngen.exe.

Any further help would be of great assistance in resolving this.

Thanks again,

Tony

I'm afraid I don't know how to detect which version .Net is installed. Removing and installing a known English version shouldn't hurt though.

You could create a simple program that causes an exception. The error message is in the same language as the Framework version.

class MainClass
{
public static void Main()
{
int n = 0;
int o = 1/n;
}
}
