Hi -- I have a serious problem here - need your help ! I use a Win XP SP 2 - Laptop - Recently I had an issue wherein the OS does not allow me to Install any programs. I thought it is an OS glitch and here is what I have done. ** Formatted C: drive and Installed the New copy of OS. ** Still issue Persits ** Learned that soon after installing the OS and drivers, the task manager is disabled and i am not able to Install any Programs. ** The Installation window closes itself ** Checked the forum to Troublesoot on this issue. ** Solution says to work with the system registry to fix this issue ** Soon after i open the system registry - and checking on what to do next - the window closes immediately ** issue is : Application window closes itself ** Donot have any AV or Malware software installed to scan the PC - unable to install the Softwares as well ( as the Window closes itself while installation) ** Wanted to Fix this issue without losing any data which I saved in D: E : and F: drives. KINDLY ASSIST ON HOW TO PROCEED WITH THIS ISSUE and FIX IT.
