You need to use the regsvr32 command line tool in order to register any COM or unmanaged (not .NET) class libraries (.DLLs) that your application uses. You will have to assign sufficient permissions to these DLLs so that the user of your application (the ASPNet user or IIS_Usrs accounts by default) can use these files.

Hi Frinny, Thanks for your reply. I have done the same by registering through regserv32 and also gave full permission to my apps folder as well as user account in IIS, Dll's but not no hope same error exist.

You are most welcome with any more suggestions please :)

What operating system is the server?
Is it 32 bit or 64 bit?
