One thing that has always been somewhat inconvenient to me in maintaining multiple versions of the software on my computer is the fact that Kilgray does not distinguish the icons at all between versions, nor do they distinguish the icons used for various auxiliary programs for memoQ, like the web search and the very useful TM external search tool. Well, I fixed that.
There are, of course, other approaches, such as using the free Resource Hacker tool to change the icons used by the EXE file. But messing with executable files isn't really advisable in most cases.
If you have artwork to convert into an icon (ICO file), this can be done using the free CONVERTICO web site:
The site can also convert ICO files into bitmap files that can be edited using Microsoft Paint or other applications. Click on the logo above to go to the site.
Changing the icons for my shortcuts give me a better overview on the Windows taskbar of what is actually running when I work with some version of memoQ:
The Windows Taskbar icons seem a little fiddly to change. It took me a few tries of pinning and unpinning the application on the taskbar before the icon appeared right for memoQ 2015 (7.8), while the newer version looked OK on the first try. It's probably some sort of Windows Registry issue. In any case, the icon change for the desktop shortcuts works every time, and that at least gives me a better visual overview so I don't launch a version of the program I don't intend to work with,
