Acrobat 9.0 Pro locks up after scanning more than 4 pages

Digital_Skream

When a client fo mine scans a document of 4 or fewer pages, everything works fine,.  But, when she geos into acrobat, and tells it to Create a new pdf from the scanner, and the document is longer than 4 pages... it scans forever.  Never releases the window, the acrobat process must be terminated in task manager.  Just updated to 9.2.0, but still does it.
Any ideas?  The scanner is a Hp inkjet all-in-one on the network.

My guess is that the scanner driver is the culprit. I suggest you download the latest-and-greatest from the HP site:
http://www8.hp.com/us/en/support-drivers.html

Make sure to pick the right version for her scanner model and OS (and the choice of 32-bit or 64-bit can make a difference). HP usually provides both TWAIN and WIA drivers, and in the same download. The installation should install both. Try TWAIN first – it's usually better. But if that fails, then try WIA. If they both fail, let me know and I'll try to come up with other ideas. Regards, Joe

What's weird is that she can scan perfectly fine from other applications, regardless of pagecount.  It is only Acrobat 9.0 pro running on Win7pro 64bit that causes the problem.

I've seen that before – some apps are more sensitive to the driver than other apps. I use PaperPort as my standard scanning/imaging app, and my personal experience is that its scan manager has more problems with older drivers than other apps have. Perhaps Acrobat is fussy, too (they're both large, complex, robust, apps). I still think it's worthwhile to try the latest 64-bit W7 driver from the HP site. I don't use full Acrobat, but I'm sure it allows you to select a source, so try both TWAIN and WIA. Regards, Joe

Updated to the most recent drivers - already was using most recent drivers, but overwrote them anyways just to be sure.  Still no joy.

OK, need to look elsewhere. Maybe it's a resource issue. How much RAM does she have? What resolution (DPI) and mode (B&W/grayscale/color) is she using? I realize you said she can scan any number of four pages with other apps, but maybe Acrobat needs more resources to operate successfully.
It was the copy of acrobat that she had.  Apparently, they had purchased the copy of Acrobat off of a "discount Website".  it looked a lot like the real thing, but when i looked at the product - was going to reinstall from scratch - I found the docs were photocopies of the originals.  Which explains why it could never update successfully.

Purchased another full version, heard them exclaim "Wow, the other one was only $45" , shook my head, and everything is ok now.

Found that it was a black market shady copy.  Replaced with legit copy of software, problem solved.
