Hi. * KDW's KDll Inst 's 'Ez KD Mode' unsets SafeDllSearchMode. If your explorer's add-on has wrong system file(for example XP File) on local folder, explorer may be crash. Please try clear check "Ez KD Registry", and reboot your pc. * If you find uxtheme.dll(kdw file) in system32, some problem may be occur. (Because any applications consider the system is xp when they find uxtheme.dll) The file must exist only the target folder. Uninstall the file. * If you installed KDW with system install mode. you should uninstall it. (You can install only SHFOLDER.dll) I have recommended use Ez install mode or Dynamic mode. * If there are some Add-on's problem, you had better create new user profile, and log on new user. WMP 10 for Windows 2000 independents on KDW' installation.
