U spelt messenger wrong lol
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 +
will ccleaner work on a 64-bit windows instillation
Yes, except for Windows XP 64-bit and Windows Server 2003 64-bit with Itanium processors.
There are two versions, one for 32 and second for 64 bit. If your version is for 32 bit, it will not work in 64 bit computer.
Yes.
most will
No.
YES
No, 32-bit printer drivers will not work in a 64-bit installation of Windows. The operating system requires drivers that match its architecture; therefore, a 64-bit version of the printer driver must be installed for proper functionality. If only a 32-bit driver is available, users may need to find a 64-bit alternative or use a 32-bit version of Windows.
You need the hardware that can support both 64 bit computing as well as the software (most especially the operating system) that can run on a 64 bit platform.
on x86-64 processors, yes. On Itanium, no.
It can do but it is really the other way around. A 32-bit operating system can work with a 64-bit processor. However, if the processor doesn't have a "soft" switching mode, you will have to manually switch the 64-bit processor to 32-bit mode via the CMOS setup. Ideally you should install a 64-bit operating system and leave the processor in 64-bit mode. This will then allow you to run 32-bit programs and 64-bit programs side-by-side.
