Notice!

In order for CompuFoil to be able to perform automatically updates, I made a change that would make windows ask to allow CompuFoil to have administrator access when it is started.   Without administrative access, when you save your new files with CompuFoil, although you think they are being saved withi the normal 'Coords' folder, they really aren't.
In Vista and Windows7/8/8.1/10, Microsoft handles the Program Files folder different than it did under WindowsXP and 2000.  Applications are no longer allowed to save data within the Program Files path, (for 64 bit systems, it wound be Program Files (x86)).   Microsoft realized that this change would break a lot of programs, so they made the operating system have the ability to fool the program into thinking that it put data into the program files path, but in reality, redirects it to a whole different location.  CompuFoil defaults to saving and loading your airfoils out of the C:\program files\CompuFoil3d\Coords folder. However, what you were saving is going to a Microsoft "Virtual Store" folder.

You will find you old data here:

C:\Users\{your login name…}\AppData\Local\VirtualStore\Program Files\CompuFoil3D\Coords

You can copy your data from there to the normal

c:\Program files\CompuFoil3d\Coords folder.

(it may be Program Files (x86) on your system)
