  That run-time error is coming out of some application program that
insists on a mouse.
  A driver sits between a piece of hardware and a piece of software
-- often an operating system, but older versions of large
applications might require drivers as well.

  So there are three obvious possibilities:

1.  Your mouse is broken.  You can replace it with a cheap one for $3
or a good one for $30.  A different mouse might require a different
driver.

2.  Your mouse driver is corrupted or missing.  Maybe a virus ate it
-- maybe somebody was cleaning up unused files and got a little
carried away.  You can probably download a new driver from the mouse
manufacturer's web site.

3.  You aren't telling the software to load the driver for your
mouse.  If we had some idea what brand of mouse, what operating
system, and what application, we might be able to tell you how to
check for and fix this without getting ANY new hardware or software.
