Hello,I have installed PMDG 747 and then I getthis error when I start FS2004 :PMDG - errorFSUIPC version is too oldYou need at least v3.48 or later.The FSUICP in the Module folder is v 3.48I use Vista Ultimate + FS2004 (FS9.1)Leif

I suggest you install 3.75 from here:http://www.schiratti.com/dowson.htmlJust expand the zip into its own folder. Go To FS9modules and move fsuipc.dll out of this folder to a safety folder outside of FS.Copy fsuipc.dll from the folder you created when you unzipped to your FS9modules folder. All registration will be maintained including application self registration.There have been many bug fixes and added features. You may wish to check the history document.Don't bother with 3.48.

System : Vista - FS9I have just started to have the same problem. These past few minutes I have re downloaded the latest FSUIPC 3.75 and installed the .dll file but still keeps returning 'FSUIPC version is too old' and closes FS.I have tried loading FS9 and PMDG 747-400 without the FSUIPC.dll installed. The PMDG 747 loads up but is missing many functions like battery power.All the other aircraft I have tried in FS9 are no problem.BTW I removed any reference to FSUIPC.dll files so I know it is the only one in the modules folder.Any other suggestions?ThanksDon

One thing you can do is read the FSUIPC.log file in the modules folder for any clues.

"BTW I removed any reference to FSUIPC.dll files so I know it is the only one in the modules folder."I am almost 100% sure you haven't ;-).We've had this reported on support@ by a couple dozen people and without fail, they all had multiple copies of FSUIPC.dll located somewhere, with one of them being older.Please check again! :-)

I overcame the problem by re-registering FSUIPC.ThanksDon

Hello,same problems here :-(. I deleted every FSUIPC File in FS9/Modules und copied the new FSUIPC.dll into Modules, but still the same problems. BTW: I've the problem since the installation of the new FS9 Update from the 747XDaniel
