RegAsm : error RA0000 : Unable to locate input assembly ‘c:\Windows\System32\Pay flow_dotNET.dll’ or one of its dependencies.

I was getting the error of

RegAsm : error RA0000 : Unable to locate input assembly ‘c:\Windows\System32\Pay
flow_dotNET.dll’ or one of its dependencies.

when following instructions from installing the Payflow_dotNET.dll dll for .NET to use.  As I was running this command:

C:\Windows\System32>c:\Windows\Microsoft.NET\Framework64\v2.0.50727\RegAsm.exe c:\Windows\System32\Payflow_dotNET.dll

There is an issue here, is that the dll, although there, was not all that usable for a 64 bit version of .NET, so I moved the file to

C:\Windows\SysWOW64

and from that folder within a command prompt was able to move forward:

C:\Windows\SysWOW64>c:\Windows\Microsoft.NET\Framework64\v2.0.50727\RegAsm.exe Payflow_dotNET.dll
