correct file/folder permission setting for a nsis installer subprocess

[hellik]

thanks for your reply.

I've tried to set permission to the file ($INSTALL_DIR\some_subfolder\file_to_be_updated) which should be updated during installation by the AccessControl plugin.

but this doesn't work as it seems the updating exe ($INSTALL_DIR\bin\exe_which_does_the_update) has no (over)write access in $INSTALL_DIR\some_subfolder\ or $INSTALL_DIR\some_subfolder\file_to_be_updated.

the update of $INSTALL_DIR\some_subfolder\file_to_be_updated has only to be done during installation.

a workaround/hack may be?:

- set permission to (over)write $INSTALL_DIR\some_subfolder\file_to_be_updated
- set write permission to $INSTALL_DIR\bin\exe_which_does_the_update
- do the file update as described by invoking bat-file and subsequently exe
- set permissions of $INSTALL_DIR\some_subfolder\file_to_be_updated and $INSTALL_DIR\bin\exe_which_does_the_update back

any other hints?

thanks
