SAP B1 on Win 64 - Possible or Not ?

Our Client is using SAP B1 -2007 ( Patch Level -10) . They want to know whether SAP 2007B will supported in Win 64 bits. Similarly whether Crystal Reports is supported by Win 64. Actually i checked for crystal reports , during the installation i am getting an error which makes crystal reports functions inactive in SAP 2007B.

Waiting for the Reply

Thanks
