As before, it is essential that you follow my instructions exactly:

You must run the entire command I provided, not a fragment of it.

OK, it is looking good so far.

I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:

If you don't have it open already, start Windows PowerShell.

Type the following command:

Get-ChildItem -Path  C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\ -Recurse

Press the Enter key.
Right click on the title bar of the PowerShell window.
This will open a context menu.
Select Edit > Select All from the context menu.
This will select all the text in the PowerShell window.
Press Ctrl+C.
This will copy the contents of the PowerShell window to the clipboard.
Open a forum reply here by clicking the Reply button.
Click the </> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the Reply button to post the output.

Please let me know if you have any questions or problems while following those instructions.

I see the problem here:

RAJIV-KASHYAP:

Notice that these two folders only contain a file LICENSE.txt:

C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\mdns-discovery\1.0.5
C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\serial-discovery\1.3.2

There should be a file named mdns-discovery.exe and serial-discovery.exe respectively in each of those folders. These tools are installed automatically the first time you start the Arduino IDE, but the installations are incomplete. That causes startup of the IDE to fail.

The most likely explanation for the missing files is that your antivirus software thought they looked suspicious and quarantined them.

Please check in the quarantine area of your antivirus software settings to see if the files are in there.

RAJIV-KASHYAP · July 25, 2022, 1:01pm

Sir, both LICENSE.txt files are in given folder.

C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\mdns-discovery\1.0.5
C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\serial-discovery\1.3.2

ptillisch · July 25, 2022, 1:14pm

Please read my previous post again very carefully. Note especially this paragraph:

After that, you can follow my instructions so that we can make progress towards getting your Arduino IDE working:

RAJIV-KASHYAP · July 25, 2022, 1:24pm

Sir, I uninstalled the antivirus. but problem is same.

ptillisch · July 25, 2022, 2:53pm

I did not and do not recommend going without an antivirus.

Anyway, that is your choice to make. We can focus our attention on getting the Arduino IDE working.

Please try this:

Delete this folder:

C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\mdns-discovery

Delete this folder:

C:\Users\user\AppData\Local\Arduino15\packages\builtin\tools\serial-discovery

Start the Arduino IDE.

Please be very careful when deleting things from your computer. When in doubt, back up!

ⓘ If looking for it with your file browser, note that those folders are hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

When you start the Arduino IDE, it will automatically install the missing tools. If you antivirus is not interfering this time, that process should complete successfully and the IDE will be fully functional.

RAJIV-KASHYAP · July 26, 2022, 6:09am

Dear sir, thanks a lot for your cooperation. after reinstall of antivirus the arduino ide running successfully .
again thanks

ptillisch · July 26, 2022, 6:38am

I'm very glad it is working now. Great work on persevering through the difficulties to finally achieve success!

Even though the antivirus was the real culprit here, the Arduino IDE should handle such a situation more gracefully, recovering automatically when possible. The Arduino developers are tracking this issue here:

github.com/arduino/arduino-cli

Recover from interrupted discovery/monitor installation

opened 12:34PM - 18 Feb 22 UTC

per1234

type: enhancement topic: code

### Describe the request Reinstall pluggable discovery and monitor tools of t…he `builtin` package if the tool executable is not found. ### Describe the current behavior Arduino CLI automatically installs [pluggable discovery](https://arduino.github.io/arduino-cli/dev/pluggable-discovery-specification/) and [pluggable monitor](https://arduino.github.io/arduino-cli/dev/pluggable-monitor-specification/) tools of the `builtin` package when missing or updatable. These tools allow Arduino CLI to find the "ports" used for communication with Arduino boards. It can happen that the installation is interrupted while in progress. 🙁 If a problem during the installation results in the creation of the tool's release installation folder without the tool executable, Arduino CLI can no longer do discovery. It will not automatically recover from this condition and the user must manually delete the incomplete installation in order to restore Arduino CLI to functionality. #### To reproduce ``` $ ./arduino-cli version arduino-cli Version: nightly-20220218 Commit: dd48868 Date: 2022-02-18T01:31:17Z $ rm ~/.arduino15/packages/builtin/tools/serial-discovery/1.3.1/* $ ./arduino-cli board list Error detecting boards: Error starting board discoveries: [discovery builtin:serial-discovery process not started: fork/exec /home/per/.arduino15/packages/builtin/tools/serial-discovery/1.3.1/serial-discovery: no such file or directory] No boards found. ``` ### Arduino CLI version nightly-20220218 ### Operating system Windows, Linux ### Operating system version Windows 10, Ubuntu 20.04 ## Additional context Originally reported at https://forum.arduino.cc/t/ide-2-0-lost-all-com-ports/960650 --- This situation is more problematic for Arduino IDE users, since the error message about the missing tool is not visible to them and they only notice the symptom of the IDE not seeing their ports. --- It might seem unlikely for this interrupted installation to occur under real world conditions, but the equivalent issue with Boards Manager producing incomplete tools installations has been reported by users periodically ever since the introduction of Boards Manager, at sufficient volume for Arduino Support to consider it worth a Help Center article: https://support.arduino.cc/hc/en-us/articles/360018444739-Error-file-does-not-exist-no-such-file-or-directory-system-cannot-find-the-file-specified

So hopefully it can be improved so that future users won't suffer so much as you did in this situation.
