If the installation says that there are files that need to be updated, click yes and reboot the PC.  If the message comes up again, then there is a problem with the Setup.exe file that is provided by Microsoft.  Edit one of the install files (Setup.Lst) using NotePad.exe as follows:

File7=@msvbvm60.dll,$(WinSysPathSysFile),$(DLLSelfRegister),,4/13/08 5:12:00 PM,1384479,6.0.98.2

Delete the line that contains the oleaut32.dll file, and rename the File#(s) that follow it, so that the remaining lines are sequential.

Save the changes and run the Setup.exe file.  This should resolve the installation problem.  If you still have questions, please contact Automata.
