It's very easy to recover deleted exe files. First off, look into the Recycle Bin. If you find the required file, select the recovered option. Next, you can look into the anti-virus Quarantine section. If not, you can reinstall the program.Most of the installers are usually available from the website you made a purchase. Some applications, such as Microsoft Office offer built-in repair tools as well. They will reinstall all core files including the EXE file.
