Hi Rachna0309
Open your application in VS or VB which ever you use, then click 'Project', click 'Properties' and then click 'Compile' then click 'Advanced Compile Options'
and make sure the target cpu is set to X86, If that still doesn't work I would suggest
following this link and downloading both the packadges and add it as a pre-requisite to your application install or install the corresponding packadge on the machine that you want to run the application on.
