Fixing the Canon scanner - CanoScan LiDE 110 (for Windows 10 on x64 system)

All of a sudden, the scanner does not work!
What went wrong?
When I pressed on the usual button to scan a document, an error message is displayed.
It says I need a WIA driver!
WTH!

Why would I need a WIA driver NOW, when I probably had it BEFORE?
Why was it removed? Was it removed on purpose?
Do I need to BUY or DOWNLOAD a WIA driver under the disguise of driver update?

What is this WIA driver? Where do I find it?
I searched for the WIA driver everywhere for hours!
It can be downloaded for FREE!

WIA stands for Windows Image Architecture. It is a programmable app.
It is used to display what is to be scanned.
It is a scanning format (that is what I think it is for).

The scanner program itself uses another imaging program.
I use Zoner Photo Studio 18 for this purpose (piggy-back OCR).

The robot at the Canon website can detect what system I have and find the correct scan app for me to download.
This is a good feature of the Canon website.
I have a Canon CanoScan LiDE 110 scanner which works on my laptop, a 64-bit system running Windows 10,

I checked the necessary scan apps for my system from the Canon website.
I don't actually know what they do or what they are for, or whether I need all 3.

I downloaded the 3 files below from the Canon website.
Then I installed all the 3 files, one by one.
The one at far right is most important - it says sd68-win-lide110-17_0.5-ea24.
That's the most recent version of the scan app that I need.

Then I re-started my laptop.
Then I opened the Control Panel and the Printer & Scanner folder.

I double-clicked on the Canon CanoScan LiDE 110 icon (black scanner).

I tried all the links I can see.
One link will display the profile to use for scanning.
I created a new profile and named it after me.
I set it as my new default profile.
I closed the message box.

Then I clicked on the other link and the scanner window showed up (just what I need).
I performed a scan.
I scanned an A4 document to see if it will scan.
Yes, it scanned ok.
DONE! My scanner works again!


Other notes about my scanner

1. The Canon CanoScan LiDE 110 scanner at home is not as good as the scanner that I use at work. But it is ok for home use and for urgent use. This is a bare minimum scanner. 
2. Buy a better scanner if you have the budget. It is worth if you are keeping track of documents or photos for research and publication.
3. The control for this scanner is bare minimum and not so easy to fine tune (can't fine tune). 
4. The other Canon MP model at work is much better.
