[plt-scheme] error install dynamic libraries v301 on Windows XP

Hi all,

When trying to install libs-301-bin-i386-win32.exe on several XP computers, I got the following error from a popup dialog:
 
Error opening file for writing:
 
C:\WINDOWS\system32\msvcr71.dll
 
Abort / Retry / Ignore.
 
Try "Ignore" doesn't work. I can't run PLT programs after the installation. I'm already using administrator account to do the installation. I need to install dynamic libraries v301 because I want to run some C programs that embeds mzscheme v301 on these computers. Could anyone please help? Thank you.
