Thanks Nuhi, but as Fork18 said it still BSOD later on... back to my initial list of issues: - RVM update pack = BSOD at the very beginning - any other udate pack = error on the [sourceDisksFiles] part of txtsetup.sif - no pack = error on the gdiplus been cab and BSOD later on Still no way to use Nlite RC4, I don't have my old version from last year but never had so many problems then!!!
