How to open HHK file?

The main problem with HTML Help Index is that the HHK file is incorrectly associated with programs. This causes the file HHK to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the HHK 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 Microsoft HTML Help Workshop

In this case, you should first verify that the Microsoft HTML Help Workshop application is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft HTML Help Workshop in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file HHK with Microsoft HTML Help Workshop. Below you will find a list of applications that support HHK files.

Programs to open HHK file

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

Step 2. Create association of Microsoft HTML Help Workshop with HHK files

However, it may happen that the application itself does not cause the HHK file to open in the Microsoft HTML Help Workshop application, but you can set it manually. 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. 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. Checking the "Always use the selected program ..." box will permanently associate the HHK file with the Microsoft HTML Help Workshop program.

Step 3. Update Microsoft HTML Help Workshop to the latest version

If, however, after binding Microsoft HTML Help Workshop with HTML Help Index 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 Microsoft Corporation website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the HHK file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the HHK file that we want to open. As a result of the scan, sometimes it is not possible to recover HHK files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the HHK file. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair HHK file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
When reading, a message appears that the file was encrypted or corrupted. The encrypted HHK 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. 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 HHK file to another location.
This problem only occurs with 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 HHK to close. However, some background programs may block the HHK file while scanning. If the problem persists, restart the machine.
