My new 'puter is 64 bit W7.

I just learned the camsoft.dll for VB6 is only good for 32 bit OS.
Their tech. support tells me the OS can switch to 32 bit. I'm not
seeing how. This HP 'puter came with OS installed and no media.

It looks to me like I'd need to reinstall and select 32 bit. Correct?
Should I look to getting another hard drive and setting up multiboot.
If i can borrow or steal a CD can I install with my COA product
number.

Other suggestions welcome.
