erl.exe is an executable file that is part of the Erlang OTP (Open Telecom Platform) system. Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. The erl.exe file is a software component of Erlang OTP.
The associated software, Erlang OTP, is used in several large telecommunication systems and is also being used in banking and e-commerce sectors. It is also associated with other software like RabbitMQ Server, SolarWinds Distribution, and Couchbase Server Enterprise Edition. For example, RabbitMQ, a widely used open-source message-broker software, is built on the Erlang OTP platform. Couchbase Server Enterprise Edition, a NoSQL cloud database, also uses Erlang OTP.
erl.exe is needed as it is a crucial part of the Erlang OTP system. It is responsible for executing the instructions contained in software like RabbitMQ Server and Couchbase Server Enterprise Edition. Without erl.exe, these programs would not function correctly.
Under normal circumstances, there is no need to remove erl.exe as it is a legitimate and essential file for the operation of certain software. Like any executable, it can potentially be exploited by malicious software to harm your computer system. If you suspect that the erl.exe file is causing problems or is a virus, it is advisable to run a malware scan to check the file's safety. If the file is located outside of the C:\Program Files\erl9.2\erts-9.2\bin directory, it could be a sign of malicious activity.
Description: Erl.exe is not essential for the Windows OS and causes relatively few problems. Erl.exe is located in a subfolder of "C:\Program Files"—for example C:\Program Files\erl9.2\erts-9.2\bin\.
Known file sizes on Windows 10/11/7 are 120,320 bytes (58% of all occurrences), 126,464 bytes and 7 more variants.
Erl.exe is not a Windows core file. The program is not visible. There is no description of the program. The software listens for or sends data on open ports to a LAN or the Internet.
Therefore the technical security rating is 65% dangerous; however you should also read the user reviews.

You could uninstall the associated program (Start > Control Panel > Uninstall a Program > Erlang OTP 20 or Erlang OTP 22).
Important: Some malware camouflages itself as erl.exe, particularly when located in the C:\Windows or C:\Windows\System32 folder.

Best practices for resolving erl issues
A clean and tidy computer is the key requirement for avoiding problems with erl. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the erl.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
