Hi Carl,
If your MSSQL 2008 is 64 bit you need to use our 64 bit drivers. If your MSSQL 2008 is 32 bit you can use the 32 bit drivers.
Sybase didn't offer 64 bit drivers until the later version 15.0.
So please see what bit your MSSQL 2008 is.
Then from there you can decide what to install.
PC-Client 15.5 and SDK 15.5 and higher are certified for a Windows 2008 machine.
When you install the PC-Client or SDK(Software Developers Kit for ASE) you need to make sure right click the autorun or setup.exe and run as administrator or the registery entries will not be put in due to the security on the Windows 2008 machine.
Once you get the drivers installed you also need to make sure the MDA scripts on the ASE are updated to your most current version of the drivers. These MDA scripts for odbc and oledb/ado.net contain fixes and improved performance for connectivity to the new drivers and the applications that use these drivers.There was a great ISUG article written by Wayne Smith called 'Hitching a ride' from 2008 that explains this whole procedure step by step.
Thanks,
Dawn
