AllMedia Grabber Standard is a VB [Visual Basic] app that adds & registers mscomctl.ocx in its program folder rather than in Windows system folder. A commonly used VB support file, if you already have software installed that needs mscomctl.ocx, removing AllMedia Grabber Standard can break that software, since it won't know where to look for that file -- part of what registering mscomctl.ocx with Windows does is to tell software that uses it where to find it. If you remove AllMedia Grabber Standard & find it broke something, search for mscomctl.ocx on your hard drive -- it should be in Windows\ System32 or SysWOW64, but other programs can put it in their own folder like AllMedia Grabber does -- and then once you find it register the file with Windows [I use an old app called RegDrop but there are all sorts of directions, apps, & tutorials on registering files on-line].
Part of being a VB app is requiring VB runtime or support files be installed. Microsoft stopped VB development several years ago -- maybe one reason was because version problems with those VB support files were so common. It sometimes doesn't help that some VB support was folded into .NET. At any rate, if AllMedia Grabber Standard doesn't work for you, VB support files may be missing or you may be suffering from a version conflict. You can download a VB runtime setup app from Microsoft.com. Do note that there are 2 major versions you can encounter, 5 & 6. You can have both present on your HDD, but only one version can be installed & registered with Windows. AllMedia Grabber Standard comes with the v. 6 VB runtime -- many people will have V. 5 installed from Dogwaffle Howler, which was a somewhat popular GOTD. [Note that Howler will run with VB 6 installed, but not all features may work the same.]
That all said, I like AllMedia Grabber, it pretty much does what it says, but I also keep it in my XP Mode VM where I have very little software installed -- frankly I didn't/don't want another VB app in win7 to worry about. VB isn't bad per se, but an awful lot of software will either register VB support files in their folder, or like Howler, install v. 5 rather than 6, regardless v.6 already being installed. [FWIW I keep Howler in a separate VM for those reasons.]
