Two days ago, accidentally with stupid my mouse click moved my whole FS9 to the OneDrive Temp and I found and brought it back C: drive and found something with flight simulator files deleted, and all is working fine running FS2004 is fine. I just click Sbuilder desktop it pops up error cannot exist. I uninstall SBuilder and restart and I did for wait bmp built in my FS9. Done and I got open SBuilder Open project under run FS9 slew. I click"Aircraft view" and it "Error communication with FSUIPC".. I checked double and double and registry FS9 done and etc.. FSUIPC is still in the Modules folder under Microsoft games/flight simulator 9. I don't UNDERSTAND it. I tried and tried and tried. Nothing luck. Can you tell me what should I do with this Windows 10 to edit regedit or something else? Remove .ini file somewhere? How? It was working 2 months ago installed everything in my new computer Windows 10. Windows 10 is a pain in the NECK! It drove me crazy right now SBuilder does not work. Please help!
