I encounter a problem while trying to install the Flash plugin – there is no plugin for 64-bit browsers. This kinda surprise me actually. Flash would be one application that I would last expect to not work in 64 bit. But yeah, it doesn’t:
Player support on 64-bit operating systems
Adobe Flash Player is not supported for playback in a 64-bit browser. However, you can run Flash Player in a 32-bit browser running on a 64-bit operating system.
Adobe is working on Flash Player support for 64-bit platforms as part of our ongoing commitment to the cross-platform compatibility of Flash Player. We expect to provide native support for 64-bit platforms in an upcoming release of Flash Player following Flash Player 10.
To use Flash Player to view Flash content on a 64-bit operating system, you must run a 32-bit browser. (Source: Adobe)
To install Flash, you can always revert to a 32 bit browser. I just somehow like the number 64 that’s all.
