Hi mate, this is actually how PMDG prefers to handle the liveries, even though single folder instalation can work too, the PTP file makes sure that even if the system is updated, the livery will keep working. I know if seems to be extra unecessay work, but keeps it future safe for you and for livery creators, now PMDG also provides the Operations Centre to Sim Market customers (as it should be from the beginning). Is not uncommon that user files make the simulator crash too..

So how do you install it?

If you have a Market Place DC-6 download the PMDG Operations Center (https://pmdg.com/downloads/)

Open the PMDG Operations Center that comes with your PMDG DC-6, Select "Aircraft and Liveries" from the top menu then click "Install from PTP file" and select the .PTP file you downloaded.

This way you make sure that the livery will keep working if PMDG or Microsoft updates their structure.

Hope you have fun with this livery!

Thanks! Unfortunately, I'm not sure whats going on with PMDG, but I have the pMDG Operations Center V2, but it says it cannot reach or connect to PMDG. I thought maybe I could re-install it, but when I click the link you provided, I get a 404. It says the page no longer exists. I wonder whats up. EDIT: Went to their website downloads section, and clicked the link for the Ops center (http://downloads.pmdg.com/operationscenterupdate/OpsCenterUpdater.zip) But I get "security risk" warnings from my antivirus. Perhaps they didn't pay their Google masters extortion fee to keep their site working. Google has basically hijacked the entire internet, and slaps "security threat" warnings on every site that doesn't pay them.
