How to open AU3 file?

The most common problem when using AutoIt V3 Script is that a specific AU3 is not associated with the program. Thus, when you open AU3, 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 AU3 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 AutoIt

In this case, you should first verify that the AutoIt application is installed on the computer. The easiest method is to use the system search engine by entering the program name AutoIt 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 AU3 files.

Step 2. Create association of AutoIt with AU3 files

If the application is or has been freshly installed, but the AU3 file still does not use the AutoIt program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the AU3 file with the AutoIt application.

Step 3. Update AutoIt to the latest version

The fault may also lie with the AutoIt program, it is possible that AutoIt V3 Script requires a newer version of the program.

Step 4. Check for the following problems with the AU3 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. This is most often caused by a problem while downloading the AU3 file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file AU3 or the program directory. As a result of the scan, sometimes it is not possible to recover AU3 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 AU3 file. Help should be sought from the software developer, as they usually recommend using free file converters or installing 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 AU3 file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted AU3 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. If possible, you can try to move the AU3 file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file AU3 to close. However, some background programs may block the AU3 file while scanning. If the problem persists, restart the machine.
