Files under Files subfolder

I have an application that includes a base install and the SK6 update. I placed the SK6 files in a sub-folder under the Files folder, but I can’t figure out how to access the sub-folder. Any ideas?

I tried the following, and few other random stabs.

Execute-Process -Path ‘$dirFiles\\AdvantX_5016.exe’
Execute-Process -Path ‘…\\AdvantX_5016.exe’

Thanks for any help!

Try Execute-Process -Path “$dirFiles\\AdvantX_5016.exe” rather than the single ‘’
