Cannot launch .CMD files
Posted on 2008-10-31
A strange thing has happened to my laptop. Whilst creating a backup script (Backup.cmd), I noticed that the usual icon for .CMD files was not displayed. It appeared the file association for .CMD was broken. I fixed it (assoc .cmd=cmdfile) and the correct icon returned, but the file still does not launch. Instead, a CMD window opens. I tried a .BAT file and the association was also broken. I repaired if (assoc .bat=batfile) and tested with a simple .BAT file and it works fine. I also noticed that the .REG association was broken. I fixed it (assoc .reg=regfile) and now .REG files merge in as expected.
I tried running my Backup.CMD script from an open CMD window and it works. It's just launching from Explorer that does not work. I have merged in a registry fragment from Kellys Korner to fix the 'cmdfile' registry bits all to no avail.
