With the BTRegSvr tool, you can register even recordable OLE controls such as DLL or OCX files (ActiveX controls) and cancel its registration. This may be necessary to resolve certain problems with Windows, Microsoft Internet Explorer or other programs.
BTRegSvr is an alternative to Microsoft's RegSvr tool. Since Windows Vista/Win7 it can happen that Microsoft's RegSvr do not succeed un/registering modules, because some of them require admin rights to execute and not all users are aware of to run RegSvr in admin mode. BTRegSvr forces to use the admin mode in Windows Vista/Win7. Give BTRegSvr a try to see what it's really capable of!
