VS Code SDK install failure

[RFLABS]

Have tried several times to install the SDK into VS code without success. This is one of the errors I am getting:

Failed to register SDK installation: west failed with code -4058 (cmd 'west zephyr-export) (cwd 'd:\ncs\v3.3.0'):

The SDK will not be detected by VSCode before the CMake Package Registry is corrected for the Zephyr package: d:\ncs\v3.3.0

[11:17:50] Unable to find the toolchain at path:  C:/ncs/toolchains/dcbdc366a1/opt/zephyr-sdk/gnu/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc.exe

[11:17:50] Unable to find the toolchain at path:  C:/ncs/toolchains/dcbdc366a1/opt/zephyr-sdk/gnu/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc.exe

I also tried reinstalling without success. Do I need to stall more than "nRF Connect for VS Code Extension Pack  v2025.4.4" before installing the SDK?

Hi David,

I noticed that the SDK and toolchain are installed on different drives. The SDK appears to be on d:\ drive, and the toolchain on C:\ drive. Could you confirm whether you have a d:\ drive at all? Could you reinstall both the SDK and toolchain under the same root directory to see whether that resolves the issue?

Please advise next steps.

Hi David,

Could you send me the full log leading up to the crash, everything before the error message "Unable to build: SDK not found. Ensure that a valid SDK is used for the build configuration."? The log may show which path is being used, which would help me debug the problem.

Thanks,
