The same message showed up when I tried to open OpenOffice 4.1.4, which I was using successfully for some time. I've uninstalled, reinstalled, and tried restarting OpenOffice 4.1.5 several times today but to no avail. The location specified in the dialogue box, AFAICS, doesn't actually exist on my hard drive either. Please tell me WTF is going on otherwise I'll have to give up on OpenOffice altogether and revert to MS Office instead, which I don't really want to do because I enjoy using OpenOffice and like its philosophy.
I didn't find the right solution from the Internet.
