Shutter Count from Dire Studio works for me on all of my post-Digic II Canon EOS cameras. Your Canon EOS 1100D is listed as compatible.

Canon cameras released since the end of 2014 do not allow shutter count functionality from the remote control interface and are not compatible with Shutter Count.

Update

Dire Studios has released ShutterCount version 3 (currently for Mac or iOS only) that can now read the shutter counts for the cameras excluded above, as well as some other more recent models. From the updated FAQ page as of July 2, 2017:

Q13 - The shutter count is not displayed for new cameras (5D IV, 5DS/R, 1D X II, etc.)

Update to ShutterCount 3.0 or later on your Mac or iOS device. The Windows version will support these cameras later on.

Dire Studios also now offers an add-on Live View Pack to their Shutter Count app that allows one to see Live View stills and Live View movie actuations of the shutters in selected cameras.

For a list of all supported cameras, please see the Compatibility List at the ShutterCount Tech Specs page.

Unfortunately, it doesn't look like Dire Studios is interested in ever updating the Windows version again, due to the high cost of Microsoft licensing. They once had a statement to this effect included in one of the FAQs, but it seems to no longer be there at their site.

As of 22 February, 2018 there has still been no update to the Windows version of Shutter Count. In fact, the older version compatible with Windows is no longer offered for sale by Dire Studios.
