If you buy RealFlight R/C Simulator and have a problem installing here is
what I had to do.
Have the jewel case the CD came in handy. There is a little tag on the back
with the serial number. It is the long number -RF-long number. Go to
www.realflight.com and register your software. This will let you get to
the free download screen. Download the installation fix.
That is all that it took, but I only found out after I used my nickel to
call tech support. This is not the first time I have purchase new software
and had to go back to the company for help. The last time it was because
the CD was bad. It took a new CD.
This is not a complaint. Just hope to save another new buyer some
frustration.
