Conditional addition of files

[RamyLernerQlik]

Hi, I'm working on an Installscript MSI project.

The automatic build of my product includes conditional packing of some 3rd party binaries (depends on the building parameters). As a result I cannot know in advance if these files are going to exist on the source machine before creating the MSI or not . Is there a way to add these files to the installer only if they exist on the source computer? I see how to set a condition based on whether a file exists on the target computer, but I didn't find a similar condition for the source computer.

Thanks!

Take a look at Dynamic File Linking:

Be aware that if you are building an installer that differs from a previously installed versioned you will need to create an upgrade.

Dynamic File linking has some limitations with Minor Upgrades, so I'd suggest creating a Major upgrade for a more robust solution.

Thank you, this is the solution I needed!
