HiI am having problems installing this.This is totally a new install now.I have tried1. FSX2. SP13. Acc packI have also tried1. FSX2. Acc packThe latter seems to cause issues with parts of the add-on aircraft panels going missing or certain missions just going to black screen but sound working.So I am thinking of sticking with the first method, unless someone can for sure say the 2nd method is the only way to go.regardskrishan

Have you fired up FSX between the installation steps?

Sounds like you have to reinstall the whole shabang, and you don

Yes I have loaded fsx between every stage and also I know it says you don't need the SP's but that method only caused issues. I wonder if anyone has installed after SP1 and it worked fine? or is this wrong, even though it seems to work for me.

Do I need to have anything else installed before accel pack is installed? I have attached my presently installed programs and these NET and c++ appliactions

Ok,I did FSX then Accel pack, was getting excellent fps as smoothInstalled traffic X, its update, no problem.Installed PMDG 747 problem, the 747 surface controls do not work.It would appear for whatever reason the format of FSX then Accel pack causes issues with PMDG 747I had tried FSX, SP1 then accel apck and no probelm working PMDG.I am now going to go withFSXSP1SP2TRAFFIC X + T X SP1PMDG 747LVEL-D 767After I confirm all is working well as before I bought accel pack, I will un-install SP2 and load accel packkrishan

Could be a SimConnect issue. I had a loooong struggle with that. My Hornet and Merlin would not have PFD

I have tried a full vista OS re-install followed by fsx ... I just tried Vista OS and updatesFSXSP1PMDG 747 + UpdateAt this point it is workingAccel packNOW PMDG 747 stops working, all control surfaces stop been movable.
