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.
