When you install the MSDN Library that comes with VS6, the default path is C:\Program Files\Microsoft Visual Studio\MSDN98. The default install path for MSDN Library updates appears to be C:\Program Files\Microsoft Visual Studio\MSDN (no "98", a different directory).

Since an MSDN Library update (Oct. 99, in this case) effectively replaces the one that came with VS6, what is the better choice:
1) install the update to the default MSDN directory and leave the MSDN98 directory alone
2) install the update to the default MSDN directory and delete the MSDN98 directory
3) uninstall the VS6 MSDN Libary from MDSN98 using add/remove programs, then install the MSDN Library update to the default directory
4) install the update to the MSDN98 directory and overwrite its previous contents

I'm leaning toward #3, the idea being to get rid of the 60MB of obsolete doc and to set things up so the default is correct for future updates. Any comments?
