Lightroom 4.2 refuses to open. I get a msg of "The application was unable to start correctly (0xc000007b). Click OK to close the application". I recently downloaded a trial version of OnOne Photo Suite 7. That works fine.

Which Operating system version are you running? Have you rebooted since the problem first started?

It could be a conflict with OnOne Photo Suite. The only way to be sure is to uninstall OnOne and see if Lightroom launches when OnOne isn't present.

It's possible you have a corruption in the Lightroom preferences. Try removing (or just moving) the preferences file and see if you can start that way. Information on how to do that is available at http://helpx.adobe.com/lightroom/kb/p....

Post back with your results, hopefully we can get you back up & running.

Thanks much for your reply. Had already uninstalled OnOne as well as PSE because of their Plugins to Lightroom. Spoke with Adobe software tech. He followed protocols and finally got the 32bit version to launch. No luck with the 64bit version. He will research and call back in 2-3 days. Since there are others that are having the same issue one would wonder 'what is the common thread'. If there is a solution I assume it will be eventually posted to Lightroom Forums. I miss Lightroom. :-(

Every time I go to open my LR4, i receive a message that says "the application was unable to start correctly (0xc000007b). Click OK to close the application." I have restarted my computer several times, and it continues to happen.

wat betekent een lightroom.exe toepassingsfout waardoor de toepassing niet correct kan starten (0xc000007b); installatie onder Windows 7 64 is niet goed gelukt; heb serienummer nog niet in kunnen geven; op zelfde PC wel PS CS 6 correct werkend met laatste update
