VB6 Upgrade to VB.NET missing OCXs

I've got a VB 6 project that was created by someone else, and I'm trying to upgrade it to VB.NET. The upgrade wizard gives an error that I'm missing the following:
comdlg32.ocx
comct232.ocx
comctl32.ocx
mscomctl.ocx

Obviously these are included in VB6. I dug up my copy of VB6 and tried to install it, but it's not compatible with my OS, Windows Vista Home Premium, SP1, 32bit.

Does Microsoft have a package of VB6 OCXs that I can install? What's the best process for this? Any suggestions?

Thanks much in advance.
