Unable to license Keil 8051 for simplicity studio

Max G

Hello,

i am unable to license Keil 8051 compiler for simplicity studio. I filled out the form: www.keil.com/.../install.htm and i also received a License ID but if i copy and paste this license ID to Simplicity Studio 4, a window opens for a fraction of a second and then both the new window and the simplicity studio license helper close and send me back to the standard IDE project interface. If i try to build my project i get these error messages:

*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: CODE SEGMENT: ?C_C51STARTUP LENGTH: 00000CH

*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: CODE SEGMENT: ?PR?MAIN?MAIN LENGTH: 000008H

*** ERROR L120: CONTENT BELONGS TO ERRONEOUS SEGMENT SEGMENT: ?PR?MAIN?MAIN

*** ERROR L120: CONTENT BELONGS TO ERRONEOUS SEGMENT SEGMENT: ?C_C51STARTUP

******************************************************************************
* RESTRICTED VERSION WITH 0800H BYTE CODE SIZE LIMIT; USED: 0008H BYTE ( 0%) *
******************************************************************************

Any help is very much appreciated!

    For licensing issues, you really need to contact Keil direct.

    I have exactly the same problem.
    After having installed Simplicity Studio, it told me to fill the form to get my license.
    I received the license by mail, which is told to be "PK51 Professional Developer's Kit", so not restricted in terms of code size.
    Simplicity studio confirmed the license activation.
    When I go to Preferences > Simplicity Studio > Toolchains > Keil 8051 v9.53 I can red:

    Keil's 8051 build tools

    C51 COMPILER V9.53.0.0 - SN: Eval Version

    CX51 COMPILER V9.53.0.0 - SN: Eval Version

    A51 MACRO ASSEMBLER V8.02b - SN: Eval Version

    LX51 LINKER/LOCATER V4.66.30.0 - SN: Eval Version

    BL51 BANKED LINKER/LOCATER V6.22 - SN: Eval Version

    LIB51 LIBRARY MANAGER V4.30.0.2

    What can I do to make Simplicity Studio recognize my valid license?
