Suddenly appears two problems with the same program: 1)In the start menu, when i double click the office and the adobe acrobat icons, the programs don´t start and 2) When i use the windows explorer, there are no icons in the archives that belongs to microsoft office and adobe acrobat but in the right column it is the correct asociation. If i double click them, the programs (word, excel powerpoint and adobe acrobat) open and i work very well with them.. I tried to reinstall (in order to repair) microsoft office, but the installer don´t work and crashes. What can i do? Thanks, Bkupfer
