Hi Carl,

what we are using to handle this scenario is the "Get File Info..." -> "File CRC-32" function. And in the SetupBuilder IDE, you can use the "Tools" | "Calculate File CRC-32" to calculate the CRC-32.

You have several options at runtime to validate the file(s) and then use (for example) If/Then/Else Statements to fine-tune the installation process.

If you need help with this, just let me know.
