Re: Have downloaded new Lightroom 5.4 from CC. When trying to launch am getting following error message and then Lightroom crashes: "an error occurred when attempting to change modules". Can't find a thread which relates to this error message.

Hi 99jon

After downloading Lightroom from Creative Cloud, I was told "download successful"

Now I notice that in the "Applications" folder the Lightroom icon appears, but there is no folder to go with it.

This suggests that the download wasn't really successful which means not everything came down.

That would explain why I can't find any preferences file either.

Have now also checked in my CC desktop app whether I have an option of downloading Lightroom again, but no good.

Any thoughts please?
