Thanks for your reply. I have solved the problem, i found somewhere hidden a dutch copy of the servicepack. So if there is anyone who needs a Dutch SP6a, give me a mail and i send it with an earlybird btw it is 36,7 MB instead of the 34 Eng version, why?? because of the stupid translations they comeup with, don't understand that technical english is not meant to be translated. I hate this nonsens.. Maybe a usefull hint. if you are installing a programm , try to copy the contents of the temp file to an other sub dir. i have done it several times. in this way there is always a back-up, incase it is not unzip or un rarrable with unzip or unrar. talking bout stupid tranlations!! Thanks all from a happy flying dutchman I forgot, with the SP6 it is possible to use USB sticks on Winnt 4.0, works fine.
