hi mark ,

it comes from a fellow flight sim guy who sells on ebay ;

it was supposed to be new old stock sealed dvd ,

disc itself looks brand new but i am starting to think there must be an issuse with the disc ,  only 1 disc in dvd box and guessing theres only 1 dvd disc,    but because it wasnt sealed thats why i am gusessing dvd disc fault,

all of my other FSX dlc discs all installed without any issuses,

the disc goes to install langaue and then 2 or 3 seconds stops , so has to be a disc issuse,

reason i am back on FSX from MF20 IS because this
year i was in hospital from covid and some nice person broke into my home and stole my pc , and all of my retro megadrive and playstation 1,2,3,4, xbox 360 and all the games which goes with all mof that,   
i enjoy old flight sims and because insurance are finding exuses not to pay out ,
i had to buy a pc which would handle fsx BUT MSFS IS ABIT TOO MUCH LOL,

SORRY about the long winded message and i guess i will send back the space shuttle disc back to the ebay seller for a refund and then come back on here and buy the download version,

all the best mark
