The module "craxdrt.dll" failed to load.

I am trying to rebuild a computer that crashed.  The old computer was Win7 Pro, new computer is Windows 10.
I had a couple of versions of Crystal Reports as well as Visual Studio 2005 and Visual Studio 2010.  I have re-installed these (CR XI, CR
I was able to save all the data files, including all the source code for all the projects I was working on but had to re-install apps/compilers/etc.

When I open VS2005 to be able to modify/re-compile an app that worked on the old computer, I get this error:
Warning      1      Cannot load type library for reference "CRAXDRT". Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))      CD_Main

in trying to research the issue, it seems that the problem is that I need to register the Craxdrt.dll.  (not sure if this is the real solution or not).

I opened a cmd window in Administrator mode and changed directory to the path where the .dll file is (c:\Program Files (x86)\Common Files\Business Objects\2.7\Bin)
I type "Regsvr32  craxdrt.dll" and I get this message:
The module "craxdrt.dll" failed to load.  Make sure the binary is stored at the specified location... The specified file could not be found.

I did a "dir" and it shows the craxdrt.dll file.

Suggestions?
Thanks!
