[ERROR] armclang: error: Failed to check out a license

Mbed Studio
#1

Hi,

I am very new to Mbed Studio. Recently, I am trying to import SX1280 library to the project.
But I failed to compile the SX1280 library. It seems to license issues.

Building project mbed-os-empty (NUCLEO_L476RG, ARMC6)
Scan: mbed-os-empty
Compile [ 0.1%]: sx1280-hal.cpp
[ERROR] armclang: error: Failed to check out a license.
armclang: note:

  • ARMLMD_LICENSE_FILE: ‘C:\Mbed Studio\tools-config\ac6-license.dat’
  • LM_LICENSE_FILE: unset
  • ARM_PRODUCT_DEF: unset
  • ARM_PRODUCT_PATH: unset
  • ARM_TOOL_VARIANT: unset

Anyone has idea how to fix that?
Thanks in advance.

You have the same problem I had, follow the first link in the “Information about this error…” prompt.

You are not allowed to run Mbed Studio from a RDP session.

Hi James,

As Chris mentioned this issue may be related to remote desktop. There is a similar thread for it: Version 0.91 suddenly unlicensed.

Thanks,
