I'm having this exact problem now myself. I'm wondering what it means here to 'pause' the BWS install, because that suggests a direct, manual pausing of the BWS process, where what I'm looking at is just indirectly leaving the BWS process alone after the 2nd failure to install SCS (leaving it at the prompt for ®etry, ©ontinue, or (e)xit), manually installing SCS, and then returning to the BWS process and selecting ©ontinue.
Is this the right way to go about it?
