How to open ER_ file?

The main problem with Microsoft Winhelp Compressed is that the ER_ file is incorrectly associated with programs. Thus, when you open ER_, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the ER_ 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 Windows Help

An often overlooked issue is to make sure that Microsoft Windows Help is installed on the computer. To do this, enter the name Microsoft Windows Help into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ER_ with Microsoft Windows Help. Later in this article you will find a list of programs that can open ER_ files.

Programs to open ER_ file

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

Step 2. Create association of Microsoft Windows Help with ER_ files

If, despite the installed application, the ER_ file does not start in the Microsoft Windows Help application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. 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 ER_ file with the Microsoft Windows Help program.

Step 3. Update Microsoft Windows Help to the latest version

The fault may also lie with the Microsoft Windows Help program, it is possible that Microsoft Winhelp Compressed requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the ER_ 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. Usually this applies to ER_ files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the ER_ file that we want to open. As a result of the scan, sometimes it is not possible to recover ER_ 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 ER_ file. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged ER_ files. You can restore the file from a backup or use Microsoft Corporation help.
The program can also signal the fact of encryption. The encrypted ER_ 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move ER_ to a different directory.
This can happen on a file that does not support multiple access. 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 ER_ to close. Some anti-virus or backup software may occupy the ER_ file for a certain period of time. If this does not work either, restart the device.
