How to Register and Unregister a DLL or ActiveX controls using Regsvr32.exe

1. Regsvr32.exe is a programme that y'all can use to register and unregister dynamic-link libraries (DLLs) and ActiveX controls (formerly called OLE Custom Controls) in the registry.
2. Regsvr32.exe is installed in the System folder. On a 64-chip version of a Windows operating system, in that location are two versions of the Regsv32.exe file: - The 64-fleck version is %systemroot%\System32\regsvr32.exe. Path: C:\Windows\System32\regsvr32.exe - The 32-bit version is %systemroot%\SysWoW64\regsvr32.exe. Path: C:\Windows\SysWOW64\regsvr32.exe
3. Regsvr32 is the control-line tool that registers DLL files equally command components in the registry.
4. Regsvr32 is used for registering a COM-based DLL. Regsvr32 generates, registers, and installs a type library into a specified COM+ 1.0 awarding.
5. To exist used with regsvr32, a DLL must export the functions DllRegisterServer and DllUnregisterServer.
6. Regsvr32 volition load the library and try to call the DllRegisterServer() from that library. It doesn't care what DllRegisterServer() really does – information technology but calls that office and checks the returned value.
7. You use it to register COM servers in unmanaged DLLs.
8. Information technology can't generate a .tlb file.
9. Most oftentimes, RegSvr32.exe fails because the LoadLibrary, DllRegisterServer, or DllUnregisterServer part fails.
10. LoadLibrary can neglect because: - If the DLL is not in the specified path, or if the specified path is incorrect. - If one of the dependencies of the DLL that you are trying to load is not met; in other words, if a dependent DLL is not present or is not in the specified path.
11. Yous can employ the Depends.exe tool to check whether or not all of the dependencies of your DLL are met.
12. Your DLL must implement DllRegisterServer and DllUnregisterServer, which contain the logic that is necessary to add or delete the required registry entries for the COM component. RegSvr32.exe finds the entry point to these functions and calls them appropriately.
13. If yous use the Microsoft Active Template Library (ATL), Wizard, to create the COM DLL, the Wizard generates the necessary lawmaking for DllRegisterServer and DllUnregisterServer.

Register a DLL using regsvr32.exe

1. RegSvr32.exe has the following control-line options: Regsvr32 [/u] [/n] [/i[:cmdline]] dllname - /u - Unregister server - /i - Phone call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall - /n - Do non call DllRegisterServer; this selection must be used with /i - /due south - Silent; brandish no bulletin boxes (added with Windows XP and Windows Vista)
   
2. For instance, to manually annals the Sample.ocx ActiveX control, you would blazon the following at the control prompt: C:\Regsvr32.exe Sample.ocx Notation: This command-line assumes that Regsvr32.exe and Sample.ocx are both in the root binder of drive C.

Unregister a DLL using regsvr32.exe

1. For example, to manually unregister the Sample.ocx ActiveX control, y'all would type the following at the command prompt: C:\Regsvr32.exe /u Sample.ocx Annotation: This command-line assumes that Regsvr32.exe and Sample.ocx are both in the root folder of drive C.

Common errors while registering a DLL using regsvr32.exe

1. The command-flag "%1" is not valid. Please review the command usage and endeavor again. Crusade: The user entered an invalid combination of command-line switches or arguments when invoking the regsvr32.exe application.
2. This command is only valid if a Microsoft Visual Studio OLE Custom Control project is opened. Cause: Microsoft Visual Studio invoked or ran the regsvr32.exe application but there were no modules included in the control line arguments.
3. To register a module, you must provide a binary name. Cause: Regsvr32.exe was invoked or called with no modules to register located in the command line arguments.
4. The command OleInitialize failed to run. Your computer might be depression on retentiveness. Close any open programs and then try again. Cause: The regsvr32.exe tool has to initialize the Microsoft COM library earlier calling the required COM library functions. Information technology also has to initialize the library when it shut downwards. Typically this results when either activity has failed. If no cause can be determined then this can sometimes be solved past restarting the figurer arrangement.
5. The module "%one" failed to load.\n\n Make sure the binary is stored at the specified path or debug it to check for issues with the binary or dependent .DLL files.\n\north%ii. Crusade: Windows had issues with loading the module identified in the command line. The specific error text will be provided as part of the bulletin.
6. The module "%1" was loaded just the entry-bespeak %2 was not constitute. \n\n Make sure that "%1" is a valid DLL or OCX file and then try again Cause: The regsvr32.exe application was not able to locate the entry bespeak to the module identified in the command line. This unremarkably results from improper entry point exportation from the module or if the file is not truly a DLL or .OCX file.
7. The module "%1" was loaded merely the call to %2 failed with error code %3. \due north\n For more than information about this problem, search online using the error code as a search term. Cause: When regsvr32.exe invoked the entry point in the DLL module an error was thrown. The specific error lawmaking volition be included with the displayed message.
8. The module "%one" may not compatible with the version of Windows that you're running. Check if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.exe. Crusade: Commonly occurs if the 32-bit version of regsvr32.exe is run with a 64-bit version of the DLL.
