    Hi @Bhargav Burugupalli , Welcome to Microsoft Q&A,

    regtlib.exe and stdole.dll provided by Microsoft are mainly used for 32 -bit COM (Component Object Model). These two tools are usually used to register and cancel the Type Library. Microsoft does not offer a 64 -bit version of regtlib.exe tools, because on 64 -bit systems, COM registration often uses other methods, such as using REGSVR32 and other tools. stdole.dll is usually included in the Windows operating system, and there is a 64 -bit version on the 64 -bit system.

    If you develop COM in 64 -bit environment, you can consider using the following alternative method: Regsvr32: For registering and canceling COM components, you can use the system's own regsvr32 tool. For example:

    regsvr32 yourdll.dll // Register
    regsvr32 /u yourdll.dll // Logging out
    

    Visual Studio Development command Tips: On the 64 -bit system, use the development command prompt provided by Visual Studio, execute the regasm tool registration .NET component, or use regsvr32 Register a COM component.
