Programs to open LKO file

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

Step 2. Create association of Microsoft Outlook Express with LKO files

However, it may happen that the application itself does not cause the LKO file to open in the Microsoft Outlook Express 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. Using the "Change" button we can set the program to handle this type. 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. Checking the "Always use the selected program ..." box will permanently associate the LKO file with the Microsoft Outlook Express program.

Step 3. Update Microsoft Outlook Express to the latest version

The fault may also lie with the Microsoft Outlook Express program, it is possible that Microsoft Outlook Express requires a newer version of the program. In this case, use the Microsoft Corporation website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not work. 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 LKO file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the LKO file that we want to open. Sometimes virus-infected LKO files cannot be recovered, so make a backup in advance.
Older version of LKO file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair LKO file corruption. You can restore the file from a backup or use Microsoft Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted LKO 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move LKO to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the LKO file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
