Remember to download programs supporting AZW3 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Amazon Kindle with AZW3 files

If the application is or has been freshly installed, but the AZW3 file still does not use the Amazon Kindle program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the AZW3 file with the Amazon Kindle application.

Step 3. Update Amazon Kindle to the latest version

Step 4. Check for the following problems with the AZW3 file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the AZW3 file. The only repair option is to download the file again.
The most common cause here is computer viruses. 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 AZW3 or the program directory. Sometimes virus-infected AZW3 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the AZW3 files changes over time. 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. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular AZW3 file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Amazon
When reading, a message appears that the file was encrypted or corrupted. The encrypted AZW3 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. Copying the AZW3 file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the AZW3 file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the AZW3 file again. Some anti-virus or backup software may occupy the AZW3 file for a certain period of time. If nothing helps, please reset the device.
