I recently left home on a five month trip. I took my MSI laptop with me so I could spend some quality flight siming time. Days before departure, I had a 500gb SSD hard drive installed into my laptop and moved the old smaller SSD to another drive. Then, I don't know why I agreed, I let them install Windows 10, the latest addition. What a shock how that turned out. (I will keep Windows 7 on my home PC to the last day. I have every thing working now except my old MSFSX program. I didn't have the installation discs, and I ended up installing FSX SE. I installed and ran without problems both the PMDG 737-NGX and the Mystic Dash 8. Both have flown fine. Yesterday, I installed the Eaglesoft Citation X. I had a few things like Reverse Thrust, Co-pilots radios and the ILS approach link not linking with the Auto Pilot Approach although with the AP off I I was able to hand fly it. Then I read a forum thread which said FSX-SE didnot work with FSSUIPC4, and they said that in the Legacy Interfaces Folder you needed to install simconnect.msi into the FSX SP1, FSX-X Pack and FSX RTM folders. Later in the evening I was Googllng all over the .net, and they said to Install FSUIPC4.958 as that was an updated program for linking with FSX-SE. So my question is should I delete Sim Connect and only use your program or leave both programs to fight it out. I'm about ready to email a neighbor and have them go to my home study and send me my discs to reinstall MSFSX. Radar Contact, my weather programs, and terrian programs seem to be working fine. Any comments or advise will be appreciated. Mike Nicholson
