VB6 Viability for the future?

VB6 is a great development platform and very attractive to use for current app development.

But how viable is it as a language to use for the foreseeable future?

I seem to remember trying to install VB6 on a Windows 7 platform but this was unsuccessful - ide not supprted etc.

Yet I come of this forum and it appears to be really alive with postings and activity which is great.

I have to migrate my legacy VB apps to the Win 7 and Win 8 platforms yet the investment in Visual Studio is starting to drag me down.

Advice on how much to invest in VB6 would be much appreciated.

Thanks
