Sorry I can't help you on getting the neccessary .dll's - I have the same question!
I need VBRUN300.dll to run an HTML Writer.
I get this advice from the help-text of the Writer: Make sure the files VBRUN300.DLL, CMDIALOG.VBX, COMMDLG.DLL, TOOLBARS.VBX, and EMEDIT.VBX are in your Windows System directory (usually "C:\WINDOWS\SYSTEM").
If you could reply with advice, that'd be GREAT!
Thanks and please excuse me as "the obvious novice" at this sort of stuff!
Best,
Joel
