If not you can download the Linux CH340 Driver (but I’d recommend just upgrading your Linux install so that you get the “built in” one).Ī couple of Mac users have said “the driver crashes my mac Sierra how do I uninstall”.įirstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. (V1.0) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11)ĭrivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. Here is an older version of the Mac driver, NOT FOR 10.12 Sierra See uninstalling information at the bottom of the page if the driver causes problems for you. I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go. Inside the zip file you will find a PDF and a “pkg” file, short version, double click the pkg file, the PDF has some extra information.įYI, the driver documented here WILL crash on OSX Sierra. Press the Windows key + I on the keyboard then go to Update & Security > Activation.

The following github has up to day pkg files for 1.3, 1.4 and 1.5 at time of writing, thanks to Joshua Wallis for bringing this to my attention…ĭirect Download Links (from the github repo above): If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit.
If you are running a 32Bit Windows: – run the SETUP_32.EXE installer.If you are running a 64Bit Windows: – run the SETUP_64.EXE installer.Older Windows Driver Version and Instructions In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.I'm reaching hating levels with MS right now, 2 weeks going around without any luck.The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don’t panic, it’s easier than falling off a log, and much less painful. So the windows pro license installed is free to use. I can't get that key from my old computer, because it was broken, I sent to be repaired and ordered to use the OEM version windows. Is sooooo hard to them give me my already bought key? the only thing the have is a troubleshoot step by step that goes in circle. the only way to upgrade it is using the key or buy a new license (is totally illogic buy a new license to get my old license.) and nobody answer from Microsoft. I already have my ms account associated to my login and is an administrator account. I want to upgrade but without my key is impossible. I'm asking for every possible way to get my product key, my actual windows is a home ed, but I need some features of my pro version. and in the order history doesn't appears the product key. They said that the product key is on the mail sent when I bought the license buy it doesn't. When I click on more details it takes me to a broken link within Microsoft website saying this page no longer exists.Īny ideas on how to fix this so I can activate the correct copy of windows? My my Microsoft account shows my purchase of windows 11 pro but it doesn't give me an access to a product key. The trouble shooter does not work and it displays the error code 0xc004c003. When it finished performing updates, my computer turned back on it now how's that I have windows enterprise installed and it will not let me activate. As I restarted, my computer said it was performing updates. I restarted my computer to see if that would fix the issue. Every time I would click I would see the same message and nothing would happen. When I clicked the button it said it was unable to download and to try again. It showed the purchase was successful and a button appeared saying install now. I bought the 99 dollar windows pro from within the Microsoft store.
I used the link in settings to upgrade my version of windows.
I just finished upgrading to windows 11 home from windows 10 home and decided I would like to purchase windows 11 pro.
