CRM for Outlook with SAP Client 10.0

There is only a 64-bit version of SAP B1 Client 10.0 available.
We are using Office/Outlook installed as 32-bit, an so is CRM for Outlook
When I open any item in CRMFO and try to open it in the B1 Client; I get the error "32-bit process cant access any 64-bit process".

Is there any workaround to still use Office 32bit together with B1 Version 10; as I did not find any system requirement to use Office-64bit in this case?
