C# COM DLL: do I use Regasm, or Regsvr32?

You need to use regasm.exe
to register both the 32 bit and 64 bit interfaces I believe you need to run each of the regasm.exe
's in:
C:\Windows\Microsoft.NET\Framework\v2.0.50727
and
C:\Windows\Microsoft.NET\Framework64\v2.0.50727
So... in your case you need to run the regasm.exe
in the Framework64\v2.0.50727
folder.
Here's an example we use to register a COM interop DLL for one of our legacy ASP apps:
regasm.exe Hosting.DeviceManager.Power.dll /register /codebase /tlb
Solution 2
If the DLL is build in format of "Any CPU", no matter if you choose regasm in
C:\Windows\Microsoft.NET\Framework\v2.0.50727
or
C:\Windows\Microsoft.NET\Framework64\v2.0.50727
DLL would be registered as 32-bit.

I am building a C# ActiveX DLL... do I use REGASM or REGSVR32 to register it?
How do I register the 64-bit interface vs the 32-bit interface?
