I loaded Office 2003 onto a SSD on my W10 computer a couple of months ago and had no problems.
You could try this on the same subject (from a Microsoft Office chat group):
Try running setup by double clicking PRO11.MSI or right click it and choose "install" menu. Not sure why this problem occurs, but I suspect it's due to another wizard/wrapper that launches with regular setup and asks to
click "finish" after installation is finished.
