AC5.06u7 is not free. You require a valid Keil MDK license that covers Arm Compiler 5. Specifically:
Many older projects rely on specific ARMCC pragmas and inline assembly syntax that are not directly compatible with the Clang-based Arm Compiler 6.
As a cumulative maintenance release, Update 7 does not introduce new features or new processor support. Instead, it focuses entirely on robustness, making it the ideal choice for functional safety applications requiring a frozen toolchain. 1.

: Install it to a unique folder (e.g., C:\Keil_v5\ARM\ARM_Compiler_5.06u7 ). Register in Keil : Open Keil µVision. Go to Project -> Manage -> Project Items .
Arm Compiler 6.20+ can consume ARMCC 5 libraries using the --legacy_alias flag. However, the safest route is to keep the entire build on 5.06u7 until you can fully port. As a cumulative maintenance release, Update 7 does
Since newer versions of Keil MDK (v5.37 and later) do not include Arm Compiler 5 by default, you must add it manually. Arm Developer Extraction: Unzip the downloaded file and run from the "Installer" folder. Path Selection:
