Further info. SB8 does install and run on the XP machines. I have not had time to move all the source files and SB scripts to the XP machine to see if the same install created on an XP machine fixes the problem.

Update: I checked the web for solutions and found a Microsoft help page that says this error happens on computers which do not have Microsoft Visual C++ 2008 installed.

I was getting the same "side-by-side configuration" error on a Virtualized copy of Windows 7 Ultimate 32 bit.

Downloaded the MS VC++2008 package and ran the install. The program offered to "repair" the existing installation of VC++ and I took that option.

The Win7 virtual machine is now installing #1 of 59 updates so I will not have another update until tomorrow.
