每次编译的时候都会有这个问题：
Build target 'Target 1'
compiling common.c...
COMMON.C(1): warning C500: LICENSE ERROR (R208: RENEW LICENSE ID CODE (LIC))
compiling main.c...
MAIN.C(1): warning C500: LICENSE ERROR (R208: RENEW LICENSE ID CODE (LIC))
MAIN.C(9): error C202: 'TRO': undefined identifier
assembling STARTUP.A51...
Target not created
本人菜鸟，求高手指点。（我win7系统，安装时有禁用网卡，有使用破解文件）
我把TRO的问题解决后，又变成这样：
Build target 'Target 1'
compiling common.c...
COMMON.C(1): warning C500: LICENSE ERROR (R208: RENEW LICENSE ID CODE (LIC))
compiling main.c...
MAIN.C(1): warning C500: LICENSE ERROR (R208: RENEW LICENSE ID CODE (LIC))

linking...
creating hex file from "ex6_11"...
OBJECT TO HEX FILE CONVERTER OH51 V2.6
COPYRIGHT KEIL ELEKTRONIK GmbH 1991 - 2001
*** ERROR: CAN'T OPEN FILE 'ex6_11'
"ex6_11" - 0 Error(s), 2 Warning(s).
好像是说注册错误，要装破解版；
MAIN.C(9): error C202: 'TRO': undefined identifier第九行错误，应是TR0, O与0应区分
破解的License与安装版本不符，不够格使用新安装的版本。另找个破解吧。
