Clicking on the shortcut icon led to.......nothing. Have been using LR about a year. It is nowhere to be found on my computer. The folders for installation, read me, etc. are still under Program Files are showing but nothing happens when I try to open them. Windows. LR 4.4. Used it one day, it was gone the next. What to do??
In the Lightroom 4.4 folder, there should be a file called "lightroom.exe". What happens when you double-click it?
