Run another patch before file installation

[stomanova]

I would like to add other Patch.exe into my installation package. This Patch.exe should first update already installed application and then copy my new files into the target folder. I tried to set Custom Action, but I am not sure - where and how to set the Patch.exe. I need to run it, wait for finish running it and after that copy new files. Can you help, please ?

Hello,

You can try setting your Path.exe as an EXE with Working Dir custom action.
See our user guide on how to do this.

Place your custom action after AppSearch standard action in InstallExecuteSequence, so any searches your action depends on are already made.

Best regards,
Gabriel
