Hi Sirineni,<br />
I don't know if the dll was created by you or a 3rd party. I just give my own experience here. If I build 32bit dll myself on Visual Studio, I will switch the platform to x86, not leaving it as AnyCPU (by default). When you identify the platform clearly, that dll is compatible on Wins 64 bit. You may use different IDE or CPU, please adjust to suitable platform in this case. Hope it helps.

Microsoft Development

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server.
