You may not want to know that such combos may or may not work. At least you have the CDs to experiment and find out what works for you. Microsoft doesn't support such mishmosh installs and the updates can shoot the system down in flames. Not the OS, just the applications.
When I purchased my computer, running XP, it had Works Suite installed which included Microsoft Word 2002. Currently, this is the only Office product installed on my pc. Word 2002 is installed in C:\ProgramFiles\Microsoft Office. I just purchased Microsoft Office 2000 Professional & I want to install the 2000 versions of Powerpoint, Excel, Outlook etc. without Word 2000 (Since I have the newer version). Can I just install the new Office 2000 programs by doing a custom install, deselect Word 2000 & put them in a non-default folder labeled Microsoft Office 2000 & all will be well? I don't want to put them in the default folder because it might overwrite files from Word 2002 (Since both default folders are Microsoft Office). Would it work using the way I suggested? Most people suggest to install Office products in order of release. ie, uninstall Word 2002, install Office 2000, reinstall Word 2002. Will it work using the easy way I suggested? Any help is greatly appreciated. I have been searching for answers to this question for a while. Thanks!
