Multiecuscan

Hello,
a few weeks ago I installed the first time multiecuscan 3.3. It worked perfectly. Today I wanted to run multiecuscan, but it will not be starting. I've uninstalled it and reinstalled again. so far without success

Does anyone have an idea of what it is?

If you've upgraded from a previous version, sometimes the desktop shortcuts don't work any more.
Try the start menu shortcut and see if it makes a difference.
