My scanner has stopped working. Each time I try to use it a dialogue box appears entitled "16Bit Windows Subsystem" and saying "Windows\System32\Autoexec.NT The system not suitable for running MSDOS and MS Windows applications...." .

I have tried reinstalling and downloaded latest drivers from canon website to no avail. The scanner was working fine until recently and the only new addition to my computer was an upgraded Palm PDA desktop installation. What does this mesage mean - and any sugestions on how to fix? As ever, thanks for your help. Running WinXP SP1.
