I use the Add or Remove Programs and the deletion of the things that can not be back?

In the download is not going to,

try easyrecover to restore the software on the assumption that you try not to make any disk read-write operation System Restore can not ah

other methods are not easy! That is just too complicated to operate Remove Programs, if the installation files are on your hard disk, reinstall it again in the absence of setup, it is only re-downloaded.

Easyrecover generally recover data and restore procedures, Feasibility is not high.
