Issue Description

I'm installing VSCode on a 64-bit Windows 10 but i get a message like this:
WARNING: 64-bit install requested on 32-bit system. Installing 32-bit VSCode

Expected Behaviour

64-bit VSCode should install on a 64-bit Windows 10

Actual Behaviour

The function Test-IsOsArchX64 is testing the OS Architechture with:
(Get-CimInstance -ClassName Win32_OperatingSystem).OSArchitecture -eq '64-bit'

Because of language version different from English the answer is not '64-bit' even though the system is 64-bit. In my case it's '64-bittinen' as my OS is in Finnish. Other languages probably have this issue too.
