I also am late to this post but I'll blame it on testing with Win10TP. I installed Photo Editor from my Office 2000 Premium disc on Win7 Home Premium to see if it worked, it did. Then I installed it on Win10TP, it worked but there were a couple of file issues before the program opened [may have deselected too many things in the Tools]. It still has the 3MB size limit. Both Win7 and Win10TP are Notebooks running the 64-bit OS. I did the Customize install and deselected everything but Photo Editor in the Office Tools section, ended up with a 44MB install size. [TIP: Office 2000 is the last not to need activation but does require the Product Key.]
