Lightroom cant launch

@Menab_Wenrey 

You’ve reactivated an approx. seven years old thread. And you wrote only "I can't open my Lightroom...".  It may seem like it's the same problem, but it may not be. Also, you're not giving us any information about your system and what you've tried so far.  Rather than reactivating an old thread that is seemingly similar, you are posting to a new thread with fresh, complete information.

Please include system information, a detailed description of the problem and if it's possible a step-by-step instructions for reproduction. Also includes the steps that you've done by your own to solve the issue. 

Please do not use file attachments as many people here will not download them. Instead, use the "Insert Photos" icon and include your screen capture in your message.

If the issue is really the same, we will merge you back into the appropriate location.

This thread will be locked. Thank you!
