How to open NU4 file?
The most common problem when using Norton Utilities DLL Root is that a specific NU4 is not associated with the program. This causes the file NU4 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the NU4 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Norton Utilities
An often overlooked issue is to make sure that Norton Utilities is installed on the computer. This can be achieved by typing Norton Utilities into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file NU4.
Programs to open NU4 file
Remember to download programs supporting NU4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Norton Utilities with NU4 files
However, it may happen that the application itself does not cause the NU4 file to open in the Norton Utilities 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. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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 Norton Utilities application as the default for handling the NU4 file.
Step 3. Update Norton Utilities to the latest version
If, however, after binding Norton Utilities with Norton Utilities DLL Root there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Symantec Corporation website and install the latest version.
Step 4. Check for the following problems with the NU4 file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the NU4 file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the NU4 file that we want to open. However, remember that not every infected NU4 file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the NU4 files changes over time. 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 NU4 file corruption. You can restore the file from a backup or use Symantec Corporation help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted NU4 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 NU4 file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file NU4 to close. However, some background programs may block the NU4 file while scanning. If this does not work either, restart the device.
