trying to install the new service pack, but a message comes up saying you have to have the B1900D installed etc etc, then the installer quits. I have purchased and installed the 1900, can anyone help me out with this problem?

(please sign your posts with your real name in the PMDG forum according to PMDG guidelines pinned at the top of the forum)We suggest you reinstall the PMDG Express B1900D (no need to reinstall first), then run the Service Pack 1.1 again. I would suggest backing up your addon livery entries in the aircraft.cfg (BUT ONLY THE LIVERY ENTRIES)Best,Vin ScimonePMDGwww.precisionmanuals.comhttp://www.precisionmanuals.com/images/forum/devteam.jpg
