U spelt messenger wrong lol
will ccleaner work on a 64-bit windows instillation
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 +
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.
most will
Yes.
No.
YES
on x86-64 processors, yes. On Itanium, no.
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.
Yes, it does.
Yes.
