Hello,Had to do a repair and now the SP2 install will not run to completion. It stops about 1/2 way thru and says it cannot be run at this time. The SP1 went fine.Never saw this before - anyone have any ideas here? Running XP on a q6600 with 4 gigs of ram and I am the Admin.Thanks in advance,Ron Sagel

Id suggest uninstalling sp1 then fsx, do a reg clean ( ccleaner does a reasonable job) reinstall fsx, run it once, install sp1 do same then install sp2, It needs a clean install generally although some get lucky.
