I have FSX Gold with Acceleration installed on Windows 10 64 bit.
This is what I would recommend.
Install FSX first and if you have more than one drive install it on the drive that does not have your operating system on it.
If you only have the C drive than DO NOT INSTALL IT IN THE DEFAULT LOCATION I know others have done this and just turned down the UAC but by doing this you can open up opportunities for bad things to happen.
Just make a folder on the C drive any where except in the PROGRAMFILES (86) FOLDER
Once FSX is installed launch it so you can activate it some say to fly a short flight but I never did.
Now the tricky part is Acceleration install it and keep your fingers crossed that after it installs and you launch FSX again it gives you the activation screen for Acceleration if it does not you will get an error message
That is what happened to me. In order to solve this problem it involves changing the registry which some people including myself would rather not do.
I had even manually installed service pack 1 and 2 but FSX would still not function correctly I kept getting all kinds of texture problems. Now I no longer have any of those issues
But trust me it was a piece of cake
here is the link you will need
https://answers.microsoft.com/en-us/win ... 720?auth=1Now when I did this after getting to the place it tells you to go to I noticed that partmgr was all ready there and I thought that was not the problem. But then I noticed that the instructions stated to put PartMgr and thought it could make a difference so I deleted partmgr and inserted PartMgr and hit enter I than got a message that no blank spaces were allowed and they would be removed . I had not put any blank spaces in but I chose to accept the message which would remove them. Than I exited the registry editor and fired up FSX and low and behold I got the activation screen i entered the key and to this day fsx works with no problems.
But Microsoft has made several updates since I had originally installed FSX so you might get lucky and not have to go through this.
Any question fell free to ask
