I am facing 2 problems, first whenever I try to Install any software on my XP based pc, the install wizrd appers for may 2 secs and vanishes then if i try it say there is already setup in progress which never completes. 2nd I cannot see my hidden folders when I got to tools folder option and enable view hidden folders it is not getting active. I try o regedit also but the windows open for a second only then vanishes and then I cannot open it again.
Restart your pc! then go to the task manager!
Right click on your taskbar then click on Task Manager,
Verify if there are programs running on processes! if you think that you don't need these program
You can end the tasks!
