How do I know which build of Chrome I'm running, 32bit or 64bit? How do I change it [duplicate]

Solution 1:

Click Menu button → About Google Chrome. It will say something like:

Version 38.0.2125.24 dev-m (64-bit)

stable-m means that you're running regular, stable build. There's also beta-m, dev-m (quite less stable than beta, but updated more often) and canary-m (very unstable, but updated very often).

64-bit versions have (64-bit) at the end.

To switch to another channel (either switch between 32/64-bit or between stable/beta/dev), go to Chrome Release Channels website and download appropriate version.

Switching to more stable channel can be problematic, so think twice before you install beta-m or dev-m. Installing canary-m is relatively safe because it installs alongside regular Chrome (other editions replace each other), but canary is very unstable, so I don't recommend it.

Switching between 32/64-bit stable-ms is safe.

Solution 2:

To know which version you are running open Task Manger (ctrl+shift+esc) and if it's the 32bit version it will have (32 bit) beside it, if it's 64 bit, it won't have anything next to it.
