I have bought windows 8 and tried to reload my canon mp640 supporting programs including Canon MP640 Navigator used to scan to pdf file etc.
Everything works fine except the Navigator program. I cannot open it but get the following message "Cannot start the MP Navigator EX" It tells me then to check that the power is on etc...all of which is ok. I can print and copy with the printer and I can even use the Canon My Printer option to clean the heads etc. Any ideas folks?
