Hi Sharief,
I am facing the same issue now. Earlier 6 months ago, the ibal Clickscan A404 used to run. Now it is saying "Click Scan has stopped working" even after I tried with compatibility mode set to Windows-8. I am using windows-8.1.
I installed latest driver downloaded from iball website for A404.
I started up the system in clean boot mode with all the instructions you suggested. I still see same error message.
I have now restarted my system in normal mode. I ran trouble shoot compatibility.
Please help :(
Thanks,
Naveen Kumar K
