I Just purchased a new Canon Lide 100 scanner after finding out my old Canon scanner is not compatible with my 64 bit system---downloaded the latest 64 bit driver from Canon but when I click onto the the MP Navigator EX 2.0 I get a 'MP Navigator has stopped working' I tried the scanner with Microsoft fax and scanner and it works fine, I downloaded the MP Navigator driver a second time and done another install but no change -- any thoughts
