All other hotfixes/updates did integrate well while working in a x86 environment, only this two did not, i'm now working in a x64 os in vmware and i am starting with a clean sp1 version and a freshly downloaded x64 sp2. Integration went well, and the two mentioned hotfixes too, it seems that these two fixes also needed a x64 enironment, though nlite did not mentioned it when showing the error messages or integrating the other fixes So job well done, i'm afraid your not as big a guru as you thought to be, but thanks anyway I'm a die hard tester, and learn by trial & error....
