Scope can be installed on 64bit operating systems or 32bit operating systems. Depending on which operating system version you installed on your computer you need to install the same version of a Scope. Meaning if you have 64bit operating system you need to install 64bit scope.
When I download or receive a product from SC website I see a different zip archives. Some mention 32bit while others mention 64bit. What is this?
This means that if you installed 64bit Scope version on 64bit operating system then you need to install 64bit version of a plugin.
Same rule applies to 32bit versions.
Please always check product system requirements and general notes.
