I have solution files created in 2003
when i try to open in 2002 it says not a valid studio file.

original file environment
.net2003, framework version 1.1, win2k

changed environment
.net2002, framework 1.0,winXP Pro

I tried to install framework1.1 but didn't help.

please guide. i am new to vb and .net
that because 2003 is newer and has more stuff than 2002 you can open 2002 solutions in 2003 and 2005(beta right now) but you can't open 2005 solutions in 2003 or 2002 and also you can't open 2003 solutions in 2002

upgrade the 2002 to 2003 for it to work, i think there's a free upgrade file you can download from somewhere on but i'm not sure
There are ways to open a 2003 solution in 2002, but it requres editing the .sln and/or .vbproj files in notepad. Do some searches on Google and I'm sure you'll find the details on this.
