Over 3 times monthly lately while trying to copy--Error pops up. Error-unable to copy. At times I went so far as to uninstall the program and re-enstall. It does good untill i really need it. I have been trying to the install updates but fails all the way. Keep saying 'files can't be located' or 'program already installed'--un-enstall - skip-etc. No matter which option 'Failed to install' pops up. Then copier works until i really need then quit again. Then something keep blocking my attempts to remove the program to reinstall.
