Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the DECL file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. 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 DECL or the program directory. Sometimes virus-infected DECL files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the DECL 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.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair DECL file corruption. You can restore the file from a backup or use help.
The program can also signal the fact of encryption. The encrypted DECL 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DECL file to another location.
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. Sometimes it is necessary to wait a while before referencing the DECL file again. However, some background programs may block the DECL file while scanning. If this does not work either, restart the device.
