Board Install - Access Denied

[MikeSW17]

Fresh (first time) Install of IDE 2.0 beta 4

When attempting to install "Arduino MBed OS Nano Boards", it fails with "Access Denied"

Failed to install platform: arduino:mbed_nano.
Error: 2 UNKNOWN: installing tool arduino:arm-none-eabi-gcc@7-2017q4: moving extracted archive to destination dir: rename C:\Users\Mike\AppData\Local\Arduino15\tmp\package-827321993\gcc-arm-none-eabi-7-2017-q4-major-win32 C:\Users\Mike\AppData\Local\Arduino15\packages\arduino\tools\arm-none-eabi-gcc\7-2017q4: Access is denied.

I tried running the IDE as Administrator too, with the same result.

same error but with esp8266:[email protected] platform

Partially solved by running in powershell:

cd C:\Users\<UserName>\AppData\Local\Arduino15
icacls .\packages\* /grant Everyone:F /r

Partially solved by running in powershell:

cd C:\Users\<UserName>\AppData\Local\Arduino15
icacls .\packages\* /grant Everyone:F /r

the same result, and use the powershell cmd it just shows: "invalid parameter '/r'. solved by this cmd:
icacls.exe .\* /grant[:r] Everyone:F

But install other platform like stm32 failed too. Finally solved just install platform by Arduino 1.x, and used it in Arduino IDE 2.x.

We had two prior reports of this in the Arduino CLI repository (Arduino CLI handles the installation for Arduino IDE):

• Error during install of arduino:avr.  arduino-cli#636
• core install fails with "Access is denied" error arduino-cli#723

In both, interference from the antivirus was found to cause the problem. The same sort of pattern has long been observed with the classic Arduino IDE. The solution is to configure the antivirus so that it won't interfere with the working of the Arduino software.

Since this is really an Arduino CLI issue, and likely to be not something Arduino has any power to mitigate, I'll go ahead and close this. We do still have one issue open at arduino/arduino-cli#723, so if anyone has ideas for what can be done to improve on this situation, feel free to comment over there.
