i have problem to run windowapplication exe file to another computer

Take a look the following post. It addresses the same problem...

The solution provided is:
------ from post
Goto control panel --admin tools --Microsoft .Net Framework 2.0
Configuration.
Expand the Runtime Security Policy Node. Expand the Machine Level node.
Expand the Code Groups node. Right click on the All_Code node and
select "New..." Follow the wizard to build the new permission set (I
normally use strong name - see the .Net help for how to add a strong
name to you're solution). After you finish the wizard, you should be go
to go (on your computer at least!) So before you exit the Framework
Configuration, right click on "Runtime Security Policy" and select
"Create Deployment Package" and follow the wizard (be sure to select
Machine Level). This msi installer has to be run on each computer that
is going to use your program, and it must be run of the local drive -
running it from the network drive will not do anything. I had our
company's Network admin set up a login script to run the installer - I
think it the easiest way to accomplish it.
