ARMCLANG: Error: Failed to checkout a license (ARM Compiler 6 + Win10)
Information in this knowledgebase article applies to:
I have installed MDK V5 and my Operating System is Windows 10, version 1803. My MDK-installation is registered as a Single User License.
After updating Windows 10 OS to version 1803, building a project using Arm Compiler 6 (aka ARMCLANG) results in error messages, i.e.:
*** Using Compiler 'V6. ', folder: 'C:\Keil_v5\ARM\ARMCLANG\Bin' Rebuild target ArmClang.exe: error: Failed to check out a license.Keil Licensing error: No TOOLS.ini file found ArmClang.exe: note: Check that your license details are correct in the License Management dialog of MDK. Additional information is available at: http://www.keil.com/support/man/docs/license/license_management.htm If you need further help, provide this complete error report to your supplier or firstname.lastname@example.org. - ARMLMD_LICENSE_FILE: unset - LM_LICENSE_FILE: unset - ARM_TOOL_VARIANT: unset - ARM_PRODUCT_PATH: unset - Product location: C:\Apps\Keil\ARM\sw\mappings - Toolchain location: C:\Apps\Keil\ARM\ARMCLANG\Bin - Selected tool variant: mdk_pro ArmClang.exe: note: - Checkout feature: LIC0=TA...-.....-..... - Feature version: 5.0201710 - Keil error code: 1
I see a Build Output window similar to this one:
Windows 10 update V1803 causes the following versions of Arm Compiler 6 to fail when used with MDK and a Keil Single-User or Keil Floating license: 6.6, 6.6.1 LTM, 6.6.2 LTM, 6.7, 6.7.1, 6.8, 6.9, and 6.10.
Update to Arm Compiler 6.10.1. Either:
This issue has been fixed in Arm Compiler 6.10.1.
With newer versions than MDK V5.25 this error is not expected to come up.
We apologize for the inconvenience.
