Checking for .NET framework ....

[chloroform]

I was wondering if there was a way to make an installer for C# applications that would check and see if the .NET framework was installed, and installs if it's not present? Also, can the framework be installed on earlier versions of Windows (before 2k)? Thanks .

I'm no good with programming, but it should be possible to check the existance of .NET Framework by programming your installer to check in:

Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322

Folder: %systemroot%\Microsoft.NET\Framework\v1.1.4322

yeah that be right aaron i think.. as for installing on other OS's, i think its possible to install on older windows, but probably only as far as 2000

So I can check for the .NET framework. I'm gussing I can write a batch file that checks the registry and installs the needed files if the framework is absent, and then launches my C# application?

i guess you could, all i'd actually suggest is when u run your program, if it cant find the Latest .NET framework registry key or keys, make it popup with a message box "Unable to continue without .Net Framework" and make it kill the app.

Or ask the user if he wants to go ahead and install the framework. I'll try that, thanks .
