How to open ARX file?

An often recurring problem with AutoCAD Runtime Extension Format is that ARX is not associated with the correct program file. Thus, when you open ARX, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ARX 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 AutoCAD

In this case, you should first verify that the AutoCAD application is installed on the computer. To do this, enter the name AutoCAD 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 ARX with AutoCAD. Later in this article you will find a list of programs that can open ARX files.

Programs to open ARX file

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

Step 2. Create association of AutoCAD with ARX files

If, despite the installed application, the ARX file does not start in the AutoCAD 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 select the desired program. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the ARX file with the AutoCAD application.

Step 3. Update AutoCAD to the latest version

If, despite the association of the AutoCAD program with the AutoCAD Runtime Extension Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Autodesk, Inc. page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The ARX file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ARX 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. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our ARX file. Sometimes virus-infected ARX files cannot be recovered, so make a backup in advance.
Older version of ARX file may not always be supported by the latest software version. 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ARX file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Autodesk
The program can also signal the fact of encryption. The encrypted ARX 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 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 ARX to a different directory.
This problem only occurs with more complex files. In this case, the ARX file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file ARX to close. Some anti-virus or backup software may occupy the ARX file for a certain period of time. If the problem persists, restart the machine.
