RegSvr 1.0 was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this software available. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. This free tool was originally developed by Ralf Ulrich Garbe.
From the developer:
Use of RegSvr
Register is the default action of RegSvr. It is executed either when double-clicking the RegSvr menu item, or by clicking on the Register item. Register will call the Windows registration command: regsvr32.exe.
RegSvr will call the command with administrator rights, so Windows will ask for the permission to execute with those rights - this elevated right is required by Windows to register an Active-X/COM server.
