Acrobat X problem with ClearScan in Windows 7

Question

Using Acrobat X (10.1.2) Standard on WIndows 7 Pro. I have been scanning documents with OCR set to 'Searchable text' for months. I like the ClearScan option better, but when I changed the scanning options to use it Windows reported 'Acrobat has stopped working' and shut it down.
It happened on page 2 of a B&W scan at 600 dpi, and on page 5 of a greyscale at 300 dpi. The B&W problem was completely reproduceable, I only tried the greyscale once.
I tried the B&W scan (three pages) using 'Searchable text', followed by Tools > Document processing > Optimise scanned PDF and chose ClearScan there, and it worked fine.
I don't see any comments on this, although there are Mac comments related to ClearScan in Acrobat 9.
Is this a known problem?

Ankit, thanks for replying.
I have a CanoScan 4400F.
To check it again I scanned some pages in B&W after changing the option to ClearScan using Configure Presets. After the second page had scanned and the progress windows showed “Initialising OCR” it crashed. Windows report was only that Adobe Acrobat had stopped working, no “Details” link to click. I searched around and did not find a crash log, just the information below. Windows did suggest a solution – that I get an update to Adobe Reader, however I do not have Adobe Reader installed!
I tried a second time, and it was fine for 3 pages but crashed on the fourth. These are multi-page scans – I click “Scan more pages”.
Using Windows 7 Pro (32-bit), fully up-to-date.
