I have installed Lightroom 6 on PC with windows 7 by 5 years. Yesterday when I tried to open as usually this app it was impossible to procede because Lightroom doesn't respond. I tried to reinstall the program but whith the same result.
If this doesn't help we need more informations about your environment.
Which operating system do you use?
Which version of Lightroom do you use?
Please post the exact version and not only phrases as "recent", "latest" and so on.
Do you get an error message? If yes, please post the exact message or an screenshot.
What has been changed on your syste msince the error occure?
BTW Windows 7 is a dead product. There's no more support, no updates and securitiy patches. It's a huge risk to connect the PC to the internet. You should install the update to Windows 10 as soon as possible,

Actually when I try to open the Lightroom, I don't receive any error message but the only thing I can see is the progrem who try to start the lightroom and in the windows activity manegement I can read " Lightroom catalog - Adobe Photoshop Lightroom doesn't respond".
In this condition I can not apply any suggested actions.
I don't know if these additional informations cold be enought to identify possible solution, in any case thanks for your support.
scroll down to the section "Adobe Lightroom 6/CC 2015 Direct Download Links". There you'll find the installation files of the latest version. Please download the appropriate file, install this version and check.
Another step is to check if you catalog has a problem. Open the Windows Explorer and rename you recent catalog file and start Lightroom. LR shows an error message that the catlog wasn't found and you can create a new catalog.
