Hello William,
I'll try helping you on this MS question and explain how it may be solved
- I think that every version of MS SQL Server installs the client part (e.g SQL Server Native Client) by default
- As you said, PB is a 32-bit process and should be used with the x86 package of SQL Server Native Client 11
- At this time, I don't know if you installed MS SQL Server Express 2012 on your Windows 8 64-bit but if this is the case, I'm assuming this is the x64 package...since your OS is 64-bit
. Hence and if this is possible, you can try to install/reinstall the x86 package of MS SQL Server Express 2012 which will normally install the 32-bit version of the client, compatible with PB.
P.S.:
- Those links may have helped me answering to you
Hardware and Software Requirements for Installing SQL Server 2012
Support Policies for SQL Server Native Client
- I also encourage you to involve Microsoft support and explain them why you need to install x86 packages on a 64-bit OS
HTH,
Jacob
