I think I tested the first time after installing windows 10 and it worked once but the next day i got the above message. Is there a trusted fix for it or do I really need to download and re-install?
The message that you are getting is because of the Microsoft C++, so I would suggest repairing the Microsoft C++ Redistributable 2013,2012 and 2010.
You can also check the article :Error: "Unable to start correctly (0Xc000007b)"
Please let us know if it helps.
Thank you Tanuj;
I tried the download but couldn't get it to install directly into LR , came back to it later and found this link; https://helpx.adobe.com/creative-cloud/kb/error-opening-applications-in-windows-10.html
With this it was very easy and now things are back on track. Thank you for pointing me in the right direction.
