Problem with instalation

It can be quite a few things. Can you tell us exactly which aircraft it is, the zip also.
Is it payware.

hmm don't understand:/ I'm just trying to instal FS 2004 but i can't ,cause this error :/

Are you having trouble installing the Flight Sim or the Baron aircraft.

If it's the flight sim, uninstall everything, do a "Search" for anything left over. Be certain to go to "MY Computer" to delete the folder there.
If the reinstall doesn't work then please list your computer specs to help us figure out what's wrong.
Good luck.

yep Flight Simulator ( i was installing FS for a first time), everyting is delated,"list your computer specs" - P4 2,4 ghz , 256 ram ,geforce FX 5200 , win xp ? ( i have MS train simulator maybe they don't like each other ? eh why there is aways problem with Microsoft products ? 😞

This should help.
Your message said "D" do you have 2 hard drives or is it reading your cd drive wrong.
Is this a new copy, if so take it back and get a replacement.

I cant explain it but a few months ago while installing fs9 at the second cd I got a similar message.
Because I have several computers at home I tried to install on another one. No problems. Now I tried to install with a cd burner (USB) on the first one and I found no problems.
To make the story short I found out that was some problem with the memory chip. After replacing it there was no problems. To be sure I put the old one back and i got the brob again

I have had several similar occurences when installing various software, especially games. Installations done from the CD RW drive usually go straight through with no errors or problems, but installing from the DVD Drive almost always fail in one way or another. I can't even use the DVD drive to read burned Data CDs. No idea why - just have to accept it and use the other drive, LOL!
