I suspect that most users of the free Arduino IDE would rather the development team concentrated their time on getting the new vesions of the IDE working reliably on OSs that the vast majority use.
Spending time making sure that the new IDE works on ancient versions of 'Windows' is daft. How far back should the team go, XP, 3.0 ?
If you dont like that the new IDE is not supported on Win 7, then dont buy it maybe.
True, and i also think it's a valid point to say , "Where is a user in their Arduino and ESP32 Journey ?"
I do strongly feel that you shouldn't need to upgrade your O/S to suit an application , instead the Application should cater to the O/S .
Now if Arduino IDE is nice and simple for new users and since they are not knee deep into the Mastering the RTOS Real Time Kernel , a 400 Page document full of Goodies
and they are not knee deep into Multi Tasking , Inter Task communication Queue's Semaphore's, Mutexes and Notifications then... Sure, Wait for the fix
In my case, I'm knee deep into it, Been Using IDE for 3 or 4 years now
and Honestly i wouldn't mind an upgrade to a cooler IDE,
Hell i was even looking at the ESP IDF C.L.I. as i've loved CLI's for a long time now
Windows 3.1 
it's not Daft, it's a fair call for a person to ask of an application that it support Windows 7
let's say as far back as Vista, I wouldn't expect earlier
But the politics of it all is they do what they want and we have to take it...
I don't want to take it , Simple as that.
Why ? You know what is Daft, Upgrading when you don't have to only because a large corporation FORCED YOU TO and you just followed suit.
that's Daft.
What do you mean ,Don't buy it ?
it's Free of Charge
Latest version I could get launch on Windows 7 is arduino-ide_2.1.0_Windows_64bit.
Did you try 2.1.1? The other affected users have reported that as being the last Windows 7 compatible version.
If you would like to give it a try, installation instructions are available here:
Hi I've been reading over other people with around the same question and they say that you're able to use it so I'm not really sure why it won't work for some people...
Go to this link and see if you can install it:
It also doesn't say that theres a requirement for Windows
Have you seen any other reports of 2.1.1 not working for Windows 7 users? If so, please provide links to them.
Are you using Windows 7 @zm476?
yes I have used windows 7 with arduino 2.1.1 right now I'm using macOS
version 13.5 Ventura so I don't have any way to show you at the moment
You will get 2.2.1 there, which is reported to be incompatible with Windows 7.
For the compatible version, you must follow the instructions I linked to in post #24.
It says this:
Windows Win 10 and newer, 64 bits
Which is intended to communicate that the minimum supported Windows version is 10. This has been the minimum supported version from the start of the Arduino IDE 2.x series. The fact that previous versions of Arduino IDE 2.x happened to work on Windows 7 and 8.1 was purely by chance.
Thanks for sharing your findings.
I did after seeing others reported success with 2.1.1. It installed and launched on my system without issue. I have not tried compiling or uploading any code to a board yet.
I use Win 7 on IDE 2.1.1 No problems
Windows 7 User here and Windows 8.1, because I am a legacy tester as well, it all comes that this is dependency error, unless a workaround is done for fixing those missing .dll errors, no more for win7 and 8.
There is no need to do testing of Arduino IDE 2.x with explicitly unsupported operating system versions. However, we very much welcome beta testing with supported operating system versions. As a matter of course, the bulk of the testing done by the team is done with the operating system on our primary machines, which tends to be the latest stable version (e.g., Windows 11, Ubuntu 22.04, macOS Ventura) so the previous operating system versions don't get as comprehensive of coverage. As we see here, a significant number of users are using outdated operating system versions so beta testing for the older supported versions is a valuable contribution.
Information about contributing to the Arduino IDE 2.x project through beta testing is available here:
The last incidentally compatible version of Arduino IDE 2.x will always be available. Instructions for installing it are available here:
