Step 2. Create association of WinACE Archiver with C04 files

Step 4. Check for the following problems with the C04 file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The C04 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the C04 file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file C04 or the program directory. Sometimes virus-infected C04 files cannot be recovered, so make a backup in advance.
Older version of C04 file may not always be supported by the latest software version. 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. Sometimes the program itself has options to repair the most popular C04 file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file C04 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the C04 file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the C04 file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the C04 file for a certain period of time. If the problem persists, restart the machine.
