When you upgrade your computer to Windows XP, you receive a message similar to the following, during the Finalizing Installation phase of the upgrade:

setup cannot copy <FileName.dll>                              ensure that the location specified below is correct                               <Drive Letter:>\i386
NOTE: The compressed <FileName.dl_> may exist at <Drive Letter:>\i386.

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&gt.dll> file.

3. Close the command prompt and press OK.
