When I go to start>PC Settings>Programs> Uninstall Programs, I see no SP1 or SP2? Do they go by a different name?

Only happen when you install FSX Acceleration

Try restarting the computer. Sometimes add ons won't show up until I have rebooted the computer... Takes like 1 minute maximum. 

If you have acceleration installed it wont show up in uninstall programs. Once you uninstall acceleration, SP1 will show up in "view installed updates" next to "turn windows features on/off". It wont show up any other time. Hope that helps.

Yes it does Jordan, does the same apply to sp2 and 3?

There's no SP3. SP2 comes up in uninstall programs IIRC, but SP1 is definitely in installed updates.

Do you want to uninstall SP1/2 ?

 

If you just want to find out what's installed, open the game menu HELP => INFO/ABOUT
