What is the quickest way to find out whether the >NET framework is installed and what version?

sorry, that was aspnet_regiis.exe -i to re-install it

browse to the folder:

c:\windows\microsoft.net\framework\

Now if you see Folder "v1.1.4322" (and it's not empty) then you have .Net Framework 1.1 installed.. ( you can check out samething from Add/Remove Programs also.., you'll see .Net Framework 1.1 in Add/Remove program if it's installed)

& if dont see above folder but you see folder with name "v1.0.3705", then you have v.1.0 installed

Or let this mini-tool do it for you:

you know, i guess they are trying to make your life easier, but really, it takes me less time to browse to a folder, than to go to a site, download a zip file, unzip the file, and run the exe.

Thanks.

BTW, there are many aspnet_*.exe in the folder you referred to, could you suggest any link that explains those .exe and how to use them?

use aspnet_regiis.exe -i, this will generally fix all of your .net version problems

Here are few links where you can research for these files, just give name of those files and check out the results.
