The System DLL user32.dll was relocated in memory. The application will not run properly, The relocation occured becuase the DLL C:WINDOWSsystem32SHELL32.dll occupied an address range reservered for Windows system DLLs. The vendor supplying the DLL should be contact for a new DLL.

In our case, we got this error message because a theme pack was installed on the computer such as BricoPacks, Crystal Clear or any of the other items available at CrystalXP. It modified the shell32.dll and made it more than 8KB in size. When certain setup.exe applications detect this, it fails with this error.
