I have FSX Gold/Deluxe and Acceleration all from discs. I have managed to get FTX Global and Vector installed and they are in the FSX Scenery library, but SP3 will not instal; keeps coming up with error " cannot find FSX reg key" . I have all these on discs also and installed them from the discs. I downloaded the Orbx reg fix tool from one of the forum threads but that won't run - just comes up with message "RegistryFixTool has encountered a problem and needs to close. We are sorry for the incovenience." The error signature is:- EventType: clr20r3 P1 :registryfixtool.exe P2: 220.127.116.11 P3: 552b9da2 P4: mscorlib P5: 18.104.22.168 P6: 52ccf750 P7: 1204 P8: 89 P9: system.windows.markup.xamlparse Invoice No: FSS0355289 Date 19/02/2015. Can anyone shed any light on the issue Thanks.
