Installer issue in Dotnet application

I have an installer that runs seamlessly in any 32bit -x86 OS. But if I tried to run the exe(installer) to any 64bit OS, yeah it runs and creates a database, but does not create a tables on it... The installer is compiled in a platform 32bit OS. Do you have any idea about this? Do I need to recompile the application in a 64bit OS? I got the below issue: "SQL Server 2005 Setup cannot continue because the installation package could not be opened. The installation package has a missing file, or you are running a 32-bit only Setup program on a 64-bit computer. To continue, verify the SQL Server 2005 package you are running is supported on WOW64. If you are certain that you are running a supported SQL Server 2005 package, and you continue to see this message, contact the application vendor." Answer: Obviously, you need to provide two types of installers 1. One for 64 bit - x64 platform 2. One for 32 bit - x86 platform. While creating the installer, you need to change the targerplatform property. Cheers, Venkatesan Prabu .J http://www.kaashivinfotech.com/ http://venkattechnicalblog.blogspot.com/
