Hey mate which software did you use to collect windows registry files?
What I did to solve problem, step by step:
1. Install fresh Windows 10 2004 using
Vmware workstation pro 15( Virtual Machine windows)
2. Install
Blue Project SysTracer Pro software to capture fresh Windows registry and other files.
3. I Install Ledger Live new version and it crashed at launch.
4. Again I open Blue Project SysTracer Pro software to capture Ledger live installation files and registry. Compare step 2 files
and step 4.
5. Looking that compare files I know exact ledger live registry files location and files installation location.
6. I open regedit in my original host windows machine and delete everything related to ledger live software.
7.Install fresh ledger live software again and it's working
Thank you mate. Deleting windows registry related ledger live help me. I don't have any problem with Windows 10 1909 version.
No probs, I'm just glad it helped put that issue away, have myself been through dismay at Ledger Live when it has refused to launch after installation. After several attempts I accidentally recollected about Windows registry, specifically that it can be cluttered with interfering records that prevent programs from proper run and decided to supervise it during my last installation, and that's exactly what I found.
