It is not recommended that you manually edit the Windows registry to delete invalid JDownloader.exe keys unless you are a professional PC service. In order to fix the root of the problem, these invalid EXE registry entries need to be repaired.

In addition, malware infection may have corrupted JDownloader Launcher v3 registry entries. JDownloader.exe errors can occur when Windows tries to search for these incorrect references to files (file locations on your PC). Basically, while the actual file path may have changed, its former incorrect location is still registered in the Windows Registry.
