Upgrade Windows 2003 SP2 to R2

During an upgrade from Windows Server 2003 SP2 to R2 version I got the following error:
Setup cannot continue because the operating system edition is different from the setup edition.

The problem was generated because R2 would like to have a SP1 server.

To fix this problem
1) Copy the R2 files off the R2 CD2 and uncheck Read-Only
2) Browse to \CMPNENTS\R2\ and edit the file R2INTL.INF, change the R2SPLevel = 1 to R2SPLevel = 2

    Thanks for the tip, Vittorio, your post helped us install R2 in our company. We've modified the file and burned the hole thing on a CD then installed R2. Cheers from France !!!
