Step 2. Create association of Microsoft Flight Simulator 2004 with RC4 files

However, it may happen that the application itself does not cause the RC4 file to open in the Microsoft Flight Simulator 2004 application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here.

If, however, after binding Microsoft Flight Simulator 2004 with Microsoft Flight Simulator 2004 Customisation Data Format there were still problems, you should update the program to the latest version. In this case, use the Microsoft Studios website or update the program from the application.

Step 4. Check for the following problems with the RC4 file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The RC4 file may be unusually small compared to the original file. This suggests truncating the RC4 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file RC4 or the program directory. However, remember that not every infected RC4 file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the RC4 file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair RC4 file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted RC4 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the RC4 file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the RC4 file while scanning. If nothing helps, please reset the device.
