Hello Barney Burrow,

 Thank you for using Microsoft Windows Vista Forums.

 I would first attempt a System Restore to a point in time prior to changing the programs name.  Using the System Restore tool may not necessarily help you determine the issue. The System Restore tool uses restore points to return system files and settings to an earlier point in time. You can use it to restore the operating system to a point in time in which you did not experience the issue. When you use System Restore to restore the computer to a previous state, programs and updates that you installed are removed.

Please let us know status.  Thanks!

It can also make changes to scripts, batch files, and other types of executable files on your computer. Thus, any recently installed programs, updates, or changes to configuration will be lost if you use System Restore. However, make note that System Restore does not affect personal files, such as e-mail, documents, or photos, so it cannot help you restore a deleted file.
