Thank you for your answer. I try make installation as you describe. Sorry but I have this next problem.

Code which I got for offline activation is simply text file with name "code_w001.txt" and installation program "Weapon for FSX 1.0 Setup" looking for text file with name "key_w001.txt".

I try simple rename file which I have got but without success.

If I try use file from your website with original name I have got error : Invalid key file. Select the key_w001.txt file received from Captain Sim.

But i HAVE NOT these file,, I have file code_w001.txt :-(

Thank you - Mike
