that .dll is probably in the GAC of the source computer and you need to add it to the GAC of the destination computer

Hi David,
Thanks for Reply.

When I tried to register the DLL,I'm getting below Error.

regsvr32 Bxx.Pxxxx.Cxxxx.Txxxx.Axxx.Axxxxx.DLL

The module
Bxx.Pxxxx.Cxxxx.Txxxx.Axxx.Axxxxx.DLL
may not compatible with the vesrion of Windows that your are running.
Check if the module is compatible with a x86(32-bit) or x64(64-bit)version of Resvr32.exe

Note:Previously Application was in vs2010  and .net 4, Now it is upgraded to vs2013 and .net 4.5.2

try just copying it to your C:\Windows\Microsoft.NET\assembly\GAC_32 directory..
where does the dll in question exist on the source machine?
