Lightroom Classic 6.14 doesn't start on new Windows 11 computer.

Year ago I disconnected from LAN my Win 7 computer where LR 6 classic was installed.

Now I wish to install LR 6.14 Classic on new Win 11 computer. After running 6.14 installation file and entering LR serial, Adobe account login is required but LR still doesn’t start. When I login to lisencing I see there my registered LR license but can’t figure out how to use it. I need LR classic as photo library only. Any suggestions, how to run installed LR classic?
