Repackaging: Best practices while converting 32-bit application to 64-bit application
Answers (3)
Your question is a little unclear because you preface it with 'repackaging' but you ask about converting an application.
If you're asking about modifying an MSI, there is nothing to do. 64-bit apps anticipate 32-bit apps to be installed and act accordingly. If you're asking about converting the program, that implies changing the application code to work as a 64-bit app. For that, you'll need to read more about programming.

Do I need to change installscript also for converting to 64-bit application? - vivekjazzwal 10 years ago

I don't known to the Installscript. But you don't need to convert 32 bit app to 64 bit, this not necessary. This info are just to repack 64 bit apps. - egiberne 10 years ago
You're not actually converting it to an X64 app. You are installing a 32 bit app onto a 64 bit OS.
Assuming you use the recommended approach of not hardcoding things, and have use the MSI properties for folders etc you don't actually have to do anything.
If you have been stringing one hardcoded script after another and then wrap that all up in an MSI, you might have some problems.
