I have a Windows 8 machine with VS 2010, VS 2012 and Office 2013 64-bit installed.

We have a large VS 2010, Excel 2010 add-in template project that we ar able to run and debug fine on a machine with Office 2010/2013 32-bit. However on this machine with Office 2013 64-bit, we get a COMException saying, Cannot find a class with Id.... I ensured the project is built for 64-bit architecture.

We had installed Office 2010 PIA (http://ift.tt/1EfOkAe) on this machine after which we are able to build and run the Excel add-in project but it generates the COMException at run-time.

We created another Excel 2013 template add-in project using VS 2012 and we are able to build, deploy and debug it just fine in Offce 2013 64-bit.

So on this setup, what can be done to make the Offce 2010 template project debuggable in VS 2010/2012.
