as mentioned in my title I want to know why my Opera beta client, who should be 64bit, none is. I viewed the installation directory and detected that its located in x86. Additionally I looked in my task manager and it shows up my opera is a 32bit version.
So I downloaded again the beta 64bit client and checked the options for installing. The installation path is located to x86. Maybe I'm stupid but there is something wrong.
For testing I downloaded the 64bit final version that is actually 51 and looked again in the options for the installation. There it shows up the right path for programs that is supposed to be 64bit.
So either there was a mistake in the opera beta client or it's not really a beta 64bit version available.
