What is CHM file?

A .CHM file is a compiled online help file that is created using the help authoring tools, such as Microsoft HTML Help Workshop. The CHM file, which is an online help solution, comprises of images, text, hyperlinks that can be viewed by various programs supported on the Windows OS and on the web browsers, such as FireFox or Safari. Further, the CHM file can be converted into other formats, such as PDF, TXT, and other text formats, using various programs available online, including the Zamzar program. 

We hope we helped you solve the problem with the CHM file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the CHM file (apart from the lack of the proper application installed).

First - the CHM file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the CHM file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the CHM file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the CHM file has not been completed and it cannot be opened properly).
