I had Adobe Lightroom 5, installed to a PC that crashed and so I went ahead and upgraded to a new PC. Its a Dell system with windows 10. Reinstalled light room 5 , used the same serial key, which was supposed to be used only for one computer. After successful installation, when I open the program, I get the notification that New update is available, version 5.7. But it wont let me proceed with download and update and the program is locked at that stage. I hope this is a simple problem and someone could help me. Thanks a in advance.
The final update for Lightroom 5 was actually 5.7.1. It can be downloaded from the following website:
Scroll down the page to where you see ">Adobe Photoshop Lightroom 5" and click on it. It doesn't look like a link, but click on it anyway and you will be able to download the updated version and then you can install it on your computer.
