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

If, however, after binding Microsoft HTML Help Workshop with HTML Help Table Of Contents there were still problems, you should update the program to the latest version. In this case, use the Microsoft Corporation website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the HHC file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file HHC or the program directory. However, remember that not every infected HHC 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 HHC files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged HHC files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program can also signal the fact of encryption. The encrypted file HHC 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. The problem is only writing to the file, not reading it. Copying the HHC file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the HHC 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 HHC file again. However, some background programs may block the HHC file while scanning. If the problem persists, restart the machine.
