TO INSTALL: unzip me262.zip to your main FS2004 install directory, overwrite when prompted.

If you don't know where your FS2004 is has been installed, it will probably be in the default install directory, which is C:\Program Files\Microsoft Games\Flight Simulator 9

If you are worried because you have gotten the get a message reading something like "you have an Aircraft" folder already and you are trying to to put another one in the same directory: you want to overwrite?"

Answer: yes.
That won't delete the existing folder: the will just merge.
I packaged the plane that way to make it very easy to install: click "yes" when prompted to overwrite, the existing folders will merge with the new ones of the same name with the result of adding stuff to specificated folders with one click - OK, one right click and a choice in the quick menu: Extract to... and then choose your FS2004 folder.
This is easy: Right click, extract to... ,

If you mess this up, you 'd better play hide and seek or something: computer are not for you.

I don't know if the standard "unzipper" that ships with windows has the "extract to..." feature; if not, you can copy me262.zip as it is (zipped) to your FS2004 folder and then right click and choose "extract" (or "unzip" or whatever). Overwrite when prompted. Then you can delete me262.zip from the FS2004 folder. When you extract the files (or "unzip") and overwrite when prompted, you won't see any new files in that directory: this is normal. The new files are in their respective sub-folders; Aircraft, Gauges etc.
