Yesterday i downloaded my company s/w and tried to work on it. Suddenly a "Open With" dialog box popped up and i choose the relevant s/w exe but the s/w didn't open. At the same time i found that every application i click thereafter the image of that changes to the co. s/w image.
I removed that and reboot my system then also same problem!!!
I also found that i am not able to open any application and i try to open any it opens with the dialog box asking to choose i.e., "open with", not "Regedit". Overall to put it in asingle statement I am not able to open any .exe files
Now it is showing a different msg that"C:/path of the progarm" and " Application not found"
I have tried every solution you have specified, none of them worked for me.
