Programs to open ALTH file

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

Step 2. Create association of QuickHelp with ALTH files

However, it may happen that the application itself does not cause the ALTH file to open in the QuickHelp application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the ALTH file with the QuickHelp program.

Step 3. Update QuickHelp to the latest version

The fault may also lie with the QuickHelp program, it is possible that QuickHelp For Mac requires a newer version of the program.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The ALTH file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ALTH file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our ALTH file. As a result of the scan, sometimes it is not possible to recover ALTH files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of ALTH file may not always be supported by the latest software version. 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 ability to automatically repair ALTH file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted ALTH 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.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move ALTH 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. Closing other programs should help. 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.
