Hello,
I am unable to launch the new version on lightroom on all my computers.
I tried clean desinstallation and reinstallation and many other things like switch off the GPU support but nothing works.

The only thing working is to put back the 14.4 version or above. Do you have an idea of the problem ?

Thank you by advance for your time.

""NVIDIA GeForce RTX 2070" driverDate="20250815000000.000000-000" driverVersion="32.0.15.8108""

That graphics driver (581.08) is a Game Ready driver, which doesn't get as much testing with creative apps like LR. Install the most recent Studio driver (580.97), which Nvidia and Adobe recommend for LR:

https://www.nvidia.com/en-us/drivers/details/252609/

Adobe is continually improving how it uses the GPU from release to release, and it might be that new code in LR 14.5 is tripping over a driver bug that doesn't affect LR 14.4.

Thank you for your help.

I updated the drivers but Infortunatly it did not works.

My computers are using very differents configurations (one is Nvidea and one is Amd) but the same issue occurs.
Both of my computers are running using windows in Japanese by the way.

@Sameer K

Thank you very much for your help.
Unfortunately it did not works on both of my computers.
They have both very different configuration and they are powerful to run lightroom with any problem until now. I guess it's not a hardware problem.

Thanks for sharing and submitting crash reports. The Crash reports point to VCRUNTIME140_1.dll as the crashing module.

Try these steps to manually recreate the MSVC++ Libraries:

In the Creative Cloud app, press CTRL + ALT + T (Win) to launch Creative Cloud Troubleshooter & select 'Close Creative Cloud and related processes' > click on Go.
Go to 'Add or Remove programs' in Windows search & find all the installations of Microsoft Visual C++ Redistributable (all years).
Uninstall them completely. Even if there is an option to repair them, please uninstall all the existing MSVC++ packages.
Download a fresh package of installers for MSVC++ from this link: https://adobe.ly/3DkgAVF
Right-click the downloaded file and select Extract All.
Reinstall all packages (32bit & 64bit) one by one & then restart the computer once.

Let me know how it goes from here. Thanks!
