HOW TO GET THE TARGET ID OF YOUR MACHINE========================================
Summary: just double-click on the i4tgtid.exe icon to get the target id.--------
If you want to run the software with a nodelock license, you need to get
the target id of your machine when ordering the license.
The following explains how to obtain this id.

There are 2 executables working both on Windows 32-bit platforms
and Windows 64-bit platforms:
1/ i4target.exe
2/ i4tgtid.exe

If you double-click on i4tgtid.exe, a message box displaying the win32mac
target id of the machine will be presented. The target id is a number
represented in hexadecimal notation. Make sure that the string "win32mac"
is also displayed alongside the target id.

Depending on the network configuration of your machine, the win32mac target id
might not be available or is equal to 00000000. This is when i4target.exe in
command-line mode is needed:

1/ Open a Command Prompt window and go to the CDROM drive directory.
2/ Run "i4target -z" This will list enabled network adapter GUIDs that can be used for the target id.
3/ Run "i4target -d {12345678-90AB-CDEF-1234-567890ABCDEF}"
where {12345678-90AB-CDEF-1234-567890ABCDEF} is one the network adapter GUIDs.
Make sure you select a network adapter that will be enabled when running
the licensed program.

4/ Run i4target or i4tgtid You should obtain a win32mac target id.
NOTE: Do not repeat step 2 once you have a valid win32mac target id.
The target id is also displayed:
1/ in the "Import Certificate" panel when installing the software.
2/ in the Tools/Options/Licensing panel when running the application.
3/ in the Nodelock Key Management tool, from the Start/Programs/CATIA/Tools Windows menu.

再次看一下你安装的破解文件对不对，是不是相应版本，还有你的升级包装好了么？
