Thanks for replying.
We are not ghosting the installation, it's a normal installation using the standard files from Adobe.
The installation process is as i described above.
I tried using the wizard again now, granting the offline exception with it, and saving it as an mst. According to point 4.2.7.1 in 4 Installation Workflows — Enterprise Administration Guide, this should occur: "The Wizard validates the serial number and saves the exception inside the MST."
I can not for the life of me see any references in the mst that an offline exception exists. PRESERIALIZATIONFILEPATH is not mentioned in the property table or anywhere else in the mst either.
All further help (if possible) will be much appreciated!
