x64 version of CAPICOM?

Hi all,

Now that we are progressively moving to x64 systems, many people ask me if there is an x64 version of CAPICOM available. The answer is no, there is not. And because CAPICOM is already deprecated (CAPICOM support on Windows 7), there won't ever be any. So if you are using a version of x64 Windows older than Windows 7/Server 2008 R2, you will have to use x86 version (which will only work with x86 apps), or move to i.e. .NET and forget about CAPICOM.

I hope this helps.

  2. Sorry, I didn’t want to sound rude… :-S I just wanted to provide people with a very simple and clear answer on the subject…

  3. So is there a 1-1 mapping between .Net and CAPICOM APIs?

    This is the info we have on CAPICOM to .NET/CryptoAPI conversion:

    Is Microsoft still providing support for CAPICOM in x86 platforms?
