Solution:
In order to resolve this issue place the runtime file a4wcrInterop.dll in the same directory where the executable is residing.
For example:  \Sage Accpac\OE61A\CustomReport\CallReport.exe.  If this is the case, then runtime file should be place under \CustomReport directory.
The above mention runtime file a4wcrInterop.dll can be located under \Sage Accpac\Runtime.
There are also other errors related to reports watch out for the hot fixes which Sage has recently released.
