I Do not receive any sort of error while launching Lightroom. Nothing happend.
Thank you for your interest
Thanks for the update.
Launch Lightroom again and open task manager > check if there is a running background process for Lightroom.exe
If not, open this link to install Microsoft Visual C++ Redistributable 2012 Update 4 : Download Visual C++ Redistributable for Visual Studio 2012 Update 4 from Official Microsoft Download Center
It works again! A big thank you and have a nice day!
