When you upgrade your computer to Windows XP, you receive a message similar to the following, during the Finalizing Installation phase of the upgrade:
ensure that the location specified below is correct
To workaround this behavior:
1. Press SHIFT+F10 to open a command prompt.
2. Type the following command and press Enter:
Copy <Drive Letter:>\i386\<FileName.dl_> %systemroot%\$win_nt$.~\i386
Where <Drive Letter:> is the drive letter where the installation media exists, and <FileName.dl_> is the compressed form of the <FileName>.dll> file.
3. Close the command prompt and press OK.
