2. Closing QTP
3. During text recognition statements
64-bit operating systems will also report, in the Windows Event Viewer, that a driver cannot be loaded and needs to be updated for 64-bits.
pal_drv.sys is the system driver that both QTP, and WinRunner, use. It was developed for the old text recognition mechanism that is no longer supported.
