i cannot run express after i have installed it

my system meets the requirements and I have installed .net framework 2.0,

why can't i run sql express?

I tried running it from command prompt but nothing happens?

hi,

how did you "run" the SQLEXPR.EXE boostrap installer? please have a look at http://msdn2.microsoft.com/en-us/library/ms144259.aspx for command prompt required and supported parameters...

as regards "system requirements", be sure they are satisfied as exposed in http://msdn2.microsoft.com/en-us/library/ms143680.aspx

and just to be sure () you can have a look at http://msdn2.microsoft.com/en-us/library/ms143441.aspx as well ...
