Creating Excel Automation add-in with VC++

Question

I am newbie to Excel addins and Visual Studio. After some search, I came up with the following steps to create Excel automation addin: (I am using VS 2012)

1. create a C++ ATL project
2. add a STL Simple object
3. right-click on the object and add a method (with a IN and RETVAL parameters)
4. build the solution
5. register the dll with regsvr32

I am able to register the dll successfully. But the add-in does not show up in the Automation Servers available list in Excel 2010 (installed on my machine on Windows 7). Excel is 32 bit.

Thanks in advance

Answer 1

I was using the wrong regsvr32. Since I am building 32bit dll, I should be using regsvr32 from \\Windows\\SysWOW64.
