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

Step 2. Create association of Office Customization Tool with OPAL files

If, despite the installed application, the OPAL file does not start in the Office Customization Tool application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. 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 OPAL file with the Office Customization Tool application.

Step 3. Update Office Customization Tool to the latest version

If, despite the association of the Office Customization Tool program with the Microsoft Office Customization Tool (OCT) Language-specific Settings 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 OPAL 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 suggests truncating the OPAL file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the OPAL file that we want to open. Sometimes virus-infected OPAL files cannot be recovered, so make a backup in advance.
Older version of OPAL 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 the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair OPAL file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted OPAL 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 of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OPAL to a different directory.
This can happen on a file that does not support multiple access. In this case, the OPAL 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 OPAL file again. However, some background programs may block the OPAL file while scanning. If the problem persists, restart the machine.
