Hi @irfan24 . You must have changed the proxy settings in the Arduino IDE preferences since the last time the IDE was in a functional state. There is a bug in Arduino IDE that causes it to get an invalid configuration if you set the preferences to cause Arduino IDE to access the Internet through a pr…

Thank you for the reply!. but still i am getting error as below arduino:avr-gcc@7.3.0-atmel3.6.1-arduino7 Failed to install platform: 'arduino:avr:1.8.6'. Error: 2 UNKNOWN: read tcp 10.68.254.58:58805->104.18.32.201:80: wsarecv: An existing connection was forcibly closed by the remote host. I …

@Benjamin269 I've tried to click your link and move the file but the link just downloads an empty zip file. I can't extract anything from it and my machine says it's empty. Any advice? I'm having the same issue where I get the following error message when IDE boots and tries to load the AVR boards,…

The link still works for me, so maybe try a different browser? The downloaded file should be 50.1MB. (I'm using Chrome on Win 10)

@Benjamin269 copied link to chrome and it downloads fine but windows says it can't open. This is what i get [image] When i try to extract the zip folder I get a message saying it can't be done because the folder is empty. [image]

I don't seem to have the same file path that you mention above though, C:\Users*username* \AppData\Local\Arduino15\staging\packages (substitute your username for username ) I don't have Appdata under my username within C:\users, this is a company machine, could this be …

C:\Users\<username>\AppData\Local\Arduino15\staging\packages is the location where the Arduino IDE Boards Manager downloads archive files before installing them to the final location under C:\Users\<username>\AppData\Local\Arduino15\packages. So you won't have such a folder if you never successfully…
