Multible Instances Install/Uninstall Component only in first Instance

[andyeaust]

Hello,

i have a question about the Multiple Instance Installation with Parameter "Generate instance at Installation Time".


We have a Component that should only be installed at the first instance because there are Files that needed by all instances.
Is that possible?

Hello and welcome to Advanced Installer forums,

In order to achieve this you can take advantage of the AI_EXIST_INSTANCES property. This property is not set when installing the default instance ( when running for the first time the installer on a machine).

So, the condition would be NOT AI_EXIST_INSTANCES since you need a condition that is evaluated as true in order to have those files installed. You can take a look on the How to conditionally install a file or a registry article which may be useful to you.

Please let me know if that helped.

Best regards,
Dan
