The Dreaded Lightroom “Change Modules” Error Friday, October 19th, 2007
If you’ve been using Adobe Lightroom since Beta 1, as I have, and if you’re using a Mac, there is a very good chance that you’ve run into the awful “change modules” error. This error usually strikes when your catalog is being updated during a version upgrade, when other Adobe software on your computer changes, or for any number of other unrelated reasons (as I discovered).
What happens is roughly this: you open the program and the splash screen remains indefinitely. If you click it, it disappears, but Lightroom’s main window does not open. You receive a very minimal menu bar including “Lightroom,” “File,” “Edit,” and perhaps “Window.” The File menu is shortened and only allows you to open a catalog. I presume that this is what Lightroom would look like if you could put it into a state where it has no catalog open. During normal operation, you basically always have a catalog open.
Once there, you can try to open your catalog, but as soon as you do, you will receive the error: “An error occurred when attempting to change modules.” Feel free to click OK on that message, it will simply drop you into a weird, incomplete Lightroom interface that has no side panels and no film strip.
Having battled this error two different times now, I am confident I can offer some advice. (more…)
