Ccleaner 64 Bit or 32?

I have a copy of CCleaner on my external drive for other computers. Should I make sure that I am installing the 32 or the 64 bit version after I check the Windows I am using? Note that I just install CCleaner on my 64 bit Windows 7 and just went to the Piriform website and just downloaded and the version of CCleaner says on the program that it is indead 64 bit.

Does the website check to see if your computer is 32 or 64?

I just don't want to put a 64 bit version on a 32 bit computer.

This 32/64 bit thing is driving me nutz.

Don't worry about it anymore jonny, ccleaner automagically checks what 'bitness' of Windows you have and installs the correct one from the installer :)

Additionally, if you keep them on an external drive like you've said, launch CCleaner.exe. It'll detect your 'bitness' and if you're on a 64bit system, it'll run CCleaner64.exe automagically

The portable (which as you're using an external hard drive you should look at) has both 32 and 64 bit exes
