How to open JHM file?
An often recurring problem with Java Help Mapping is that JHM is not associated with the correct program file. This causes the file JHM to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the JHM 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 Java
In this case, you should first verify that the Java application is installed on the computer. To do this, enter the name Java into the 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 JHM.
Programs to open JHM file
Remember to download programs supporting JHM files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Java with JHM files
If, despite the installed application, the JHM file does not start in the Java application, you must create a file 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. 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 JHM file with the Java application.
Step 3. Update Java to the latest version
If, however, after binding Java with Java Help Mapping there were still problems, you should update the program to the latest version. In this case, use the Oracle Corporation website or update the program from the application.
Step 4. Check for the following problems with the JHM 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:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the JHM file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file JHM or the program directory. Sometimes virus-infected JHM files cannot be recovered, so make a backup in advance.
Older version of JHM file may not always be supported by the latest software version. 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 JHM files. The easiest way is to restore the file from a backup, if there is one, or contact Oracle Corporation
The program can also signal the fact of encryption. The encrypted JHM 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 JHM to a different directory.
This problem only occurs with more complex files. In this case, the JHM file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
