There are different versions of Vista as well as 32-bit and 64-bit for each. To switch from 32-bit to 64-bit you would have to make sure that you have 64-bit compatible hardware and would have to purchase a 64-bit version of Vista.
If you want everything works properly, then the answer is yes. Note: Yes
cant
It should say
On the control panel select "System"; this will display basic information about your computer. Under System Type, you'll see whether the system is 32 or 64 bit.
Yes; you must use an upgrade disk, and it has to be the same "bit" that your current OS is (e.g. 32-bit upgrades to 32-bit, 64-bit upgrades to 64-bit).

It depends on whether your Vista is 32 bit or 64 bit. All our their pens are currently compatible with Vista 32. They are currently developing a driver that will allow the Pens to work with Vista 64.
i assume you are trying to say "versions"= Vista Starter(This is only in 32 bit version), Vista Basic, Vista Home Premium, Vista Business, Vista Ultimate, all of them in 32 bit or 64 bit versions. or if you really mean "Types" of vista then you are talking about 32 bit and 64 bit= 2 Types
32 bit applications will work on 64-bit but they will not run as efficient as 64-bit application. the reason for this is the 64-bit uses the memory better than a 32-bit. this is why a 32-bit can only use up to 3 gigs of ram and a 64-bit can use 16 gigs +
