Here is a small too I made for registering and unregistering ActiveX and COM controls.
Unlike RegSvr32.exe included with windows RegTool features a drag n' drop interface and a file chooser to make registration easy. for those who need or prefer command line options are also available.
RegTool registers files directly using the Windows API so it is not dependent on RegSvr32.exe although if you wish you can use the -p flag to force RegTool to use RegSvr32.exe tp register/unregister files.
Register Tool, Register ActiveX and COM componants with ease!
