To register a COM DLL, you need either Microsoft Visual Studio or .NET Framework installed on the system.
Perform the following steps:
1. Open the Visual Studio Command Prompt
2. Register the DLL in the Visual Studio Command Prompt as:
regasm /codebase <DLL file name with the absolute path>
Open Command Prompt in Administrator mode & then go to the directory where .NET Framework is installed i.e. to “C:WindowsMicrosoft.NETFramework” & register the DLL using:
regasm /codebase “Location of the DLL in the system”
Note : Go to “C:WindowsMicrosoft.NETFramework” & make sure that .NET Framework (preferably 4.0) is installed on the system. If it is not installed, then install it & repeat Step 1.
