OT: Mac installer rights?

[Tiemo Hollmann TB]

Hello,

 

I am not very good in the OS X depth. I have a customer, where the
installation of my LC product with an installer from installer maker fails
in /Applications/MyFolder because "dir can't be created" (even when this dir
was created manually before, this message is logged for every file). My
customer tells me she has admin rights and creating the same dir and copying
files into it manually works fine. She has used the HD repair tool without
success.

 

My question to the Mac guys: What is the difference concerning writing
rights when the same user creates manually folders and files or lets an
installer do that for him? Is there on Mac something similar as on Windows
like "run as Admin" to try to lift the user rights? Or is here something
completely messed up? I have never experienced this before.

 

Thanks for enlightening

Tiemo
