Hello!

I am trying to install .net 2.0 on XP, but when it finishis unpacking, it does nothing. No errorcode, nothing. Just closes the unpacker window, and stops there. I can't get why. I don't know what else could I write about this problem, so feel free to ask.

It is possible that the correct .NET framework is already installed, and the installer has nothing more to do.
You can check quite easily, but you need IE (if definitely doesn't work in Chrome)

Bring up IE and paste into the address bar:

javascript:alert(navigator.userAgent)

Press ENTER.
You will get a popup saying something along the lines of:

Mozilla/4.0 (compatible; MSIE8.0; Windows NT 5.1; Trident/4.0;

Followed by a number of ".NET CLR" versions. If 2.0 is in there (and it is quite probable) then the installer just didn't need to do anything!

Ha! What a funny method of detection of the Framework. Like it! My 5.

Well, you can't write a C# program to do it... :laugh:

That probably would be exactly my first thought: write an application for each target platform and watch which of the applications would show a spectacular failure. :-)

Good answer.

Actually, I haven't think about it already, maybe you are right. I will check it tomorrow (because the computer is far away from me). First when I started my c# application it threw an error, and I thought it was the framework, but then no. Well, tomorrow I check that error code again.
Thanks, question answered.

That's quite a tip there, have my 5!

Personally, I don't like that you can execute code in the address bar: I think it is a potential security risk. But, if you are on the phone to a custard (a cross between a customer and a b@stard) then this is a simple method that even a pretty non-technical person can cope with!
The only other ways for a user to check are in the registry (and some people should not be allowed near Regedit), or to check for a folder called "%windir%\Microsoft.NET\Framework\" and see what sub-directories exist. Since this means them looking into the Windows directory, I don't like to go there either!

Custard LOL, I'll have to remember that one!

BTW there are people that shouldn't even be let near to anything resembling a computer not to mention letting them fiddle around with the registry of one. :)
