Hello Everyone / Peter Peter, I have just joined this forum, and have recently started to use your application FSUIPC, through some other freeware SIM add-ons using your application. I have also seen your notice of you being away until July, so I can wait until then unless there is someone else able to reply to me. I am not yet a registered user of your application, but I am a little confused, as these mentioned freeware add-ons supply a key to be input to your FSUIPC, to register one of their files into it. For example I downloaded a Boeing 737 Fuel Planner and the readme had a key to register a .dll file into your product. But I could not, for the life of me, find a way to do this in version 3.98 (for FS2004) and version 4. I had a similiar experience with a Russian fellow and his aircraft, also in the readme, a key to register a file, for correct function of his aircraft. I have scoured the web, and there are explanation and pictures showing how to do this. But I have presumed, and hopefully presumed correctly, that this was a function of an older version of FSUIPC, and it is now no longer the way to do this, or your product has to be registered first, to allow these files to be registered. I look forward to a reply, and some help with this. Regards Andrew Brown aka Screwbottle South Africa
