To check whether your OS is 32-bit or 64-bit, run getconf in the following way: getconf LONG_BIT

The getconf command is basically used to query system configuration variables. If the output is x86_64, then the OS is 64-bit. If the aforementioned command produces i686 in output, then your OS is 32-bit. You can use the command with -i option to produce the required information: uname -i Uname is a command-line utility that prints system information.

SPath = "Software\Microsoft\Windows\CurrentVersion\Uninstall" Set objWMI = CreateObject("winmgmts:!\\.\root\default:StdRegProv") For simplicity, though not efficiency, this with WMI seems to work Function Office32or64() As LongĬonst cFind As String = "00FF1CE}" ' note zeros and number 1Ĭonst HKEY_LOCAL_MACHINE As Long = &H80000002 If the Installer's script can enumerate keys one way or another, eg behind the scenes with EnumRegKeyEx, it might be quite simple.
