How to open H1S file?

The main problem with Windows Assistance Platform Help Format is that the H1S file is incorrectly associated with programs. This is manifested by the fact that H1S files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the H1S 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 Assistance Platform

An often overlooked issue is to make sure that Microsoft Assistance Platform is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Assistance Platform in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open H1S files.

Step 2. Create association of Microsoft Assistance Platform with H1S files

If, despite the installed application, the H1S file does not start in the Microsoft Assistance Platform application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. 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. The "always use the selected program ..." field will set the Microsoft Assistance Platform application as the default for handling the H1S file.

Step 3. Update Microsoft Assistance Platform to the latest version

If, despite the association of the Microsoft Assistance Platform program with the Windows Assistance Platform Help Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the H1S file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the H1S file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. 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 H1S or the program directory. Sometimes virus-infected H1S files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the H1S files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged H1S files.
The program indicates that the file is encrypted or corrupted. The encrypted H1S 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. The problem is only writing to the file, not reading it. Copying the H1S 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. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the H1S file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
