Big Up to mselfidem and Yzöwl for Helping out. As i said am no Computer Geek or Guru, so there was no way i was going to spot any error in any batch code. But thanks to Bro Yzöwl . And Thx to myselfidem. To help me. Two questions i have to my friends. 1.I see the start & wait cmd is not there. will the installation still wait for the first installation to finnish then go to the other one. or will it start the second installation even if the first did not finnish? 2. Will these script search into subfolders containing the .MSU files? if not, Can anyone modify the batch to make it search into subfolder and install the .MSU files. Please if somebody will modify the batch code and post, i kindly ask him or her to post the full batch code and not only the modification, Becoz i will not understand. i'll just copy the batch and save it. Once again i thank all who helped me.
