@Petr: The first three lines of your registry code should be removed. The last 5 lines, though, should not be. What needs to be changed in all the .inf files: DELETE (ALL): HKCR,"CLSID\{9BA05972-F6A8-11CF-A442-00A0C90A8F39}",,,"Window List in Shell Process" HKCR,"CLSID\{9BA05972-F6A8-11CF-A442-00A0C90A8F39}\InProcServer32",,0x00020000,"%11%\SHDOCVW.DLL" HKCR,"CLSID\{9BA05972-F6A8-11CF-A442-00A0C90A8F39}\InProcServer32",ThreadingModel,,Apartment CHANGE (ONLY IN NT INF's): HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",PackageVersion,0x00010001,3 (3->1) ADD (ONLY IN 9X INF's): HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",,,"%COMPID%" HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",IsInstalled,0x10001,01,00,00,00 HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",Version,,"%VERSION%" HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",ComponentID,,"%COMPID%" HKLM,"Software\Microsoft\Active Setup\Installed Components\%GUID%",PackageVersion,0x00010001,1 That looks like all that needs to be done. the_guy
