Upgrade PREPARE phase CHKSYSTYPE ERROR

I upgrade R/3 enterprise 4.70 to ECC6.0, when running prepare phase CHKSYSTYPE, it stops with this error, the error info is following:

> repeat

>> 10:50:38 PREPARE: START OF PHASE CHKSYSTYPE

>Error during CreateProcess of "D:\usr\sap\T01\SYS\exe\run\saplicense -number NAME=T01"

>NT errornr 193

I think it maybe be SAP version or installation problem, because my R/3 enterprise 4.70 belongs to one installation number , but ECC 6.0 UPGRADE version belong to another installation number, is it right?

Will the different installation number make this problem???? how to correct? I only want to do a test for upgrade, not use for PRODUCT SYSTEM.

Please tell me how to do ?

thanks a lot
