Step 2. Create association of Microsoft Excel with SLS3 files

If the application is or has been freshly installed, but the SLS3 file still does not use the Microsoft Excel program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Microsoft Excel application as the default for handling the SLS3 file.

If, despite the association of the Microsoft Excel program with the Microsoft Excel 3 For Mac Template file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

Step 4. Check for the following problems with the SLS3 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 SLS3 file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file SLS3 or the program directory. As a result of the scan, sometimes it is not possible to recover SLS3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of SLS3 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.
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 option of recovering data from damaged SLS3 files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft Corporation
When reading, a message appears that the file was encrypted or corrupted. The encrypted file SLS3 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. 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 SLS3 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. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the SLS3 file while scanning. If this does not work either, restart the device.
