HI! Pete: I bet you are tired of covering this, but I simply am at a loss! I am sure I am doing something incorrect, but am at a loss as to what. I have installed your program in ME and XP but this is something else. So here goes; I read your installation instructions, which seem easy enough, I turned off the Vista firewall, and this is a new computer and I only have Vista and FSX installed at this time, downloaded your program into a file I call my files, I proceeded to place fsuipc4.exe on the desktop, and installed; the Modules file was created, I opened the file and what you said should be there was, I then opened the installation doc and found it to be in gibberish, went back to the zip file, opened the same doc and it was fine. I turned up FSX and the ADD-ON was there clicked on that and fsupic opened up. The following was observed; there was the version and normal defaults and clear all WX and the check boxes for multi display and single line msgs. Registration spots were blanked out, and I expected that, do to the Admin problem. In summary all the information in the zip seems to be ok! but in the Modules file the information can't be read, and in FSX I would think your page would have had more on it, however I worked on getting a higher position as an administrator, so I might register, but have not accomplished that yet. Any help you could provide would be appreciated. :cry:
