Regarding the error message on HP Image Zone:
PARAMETER CANNOT BE NULL, PARAMETER NAME: SERIALIZATIONSTREAM that renders the program un-openable, you should try this!
I am no computer expert by any means, just your average home computer user, but I FOUND A VERY SIMPLE FIX that worked for me and is definitely worth a try! I have a PSC 1350 and my Image Zone program started showing this error after working perfectly for 8 months! I, too, have spent an entire week and given up sleep trying to find information from HP, Microsoft, and Best Buy Geek Squad to no avail. I have removed and downloaded the printer at least 50 times, in several different ways including level 2 and level 4 removal. I have downloaded every patch & update available for both Microsoft and HP. I have searched every forum, googled the error, and tried every piece of advice that I have come across. I was about to dump my hard drive, and in my quest to figure out how to back up my hard drive to a disk, I came across this simple solution that requires NO UNINSTALLING OR REINSTALLING of anything.
1. Right click on your Image Zone icon on the desktop and click Properties
2. The target listed should look like this
"C:\Program Files\HP\Digital Imaging\bin\hpqthb08.exe" What you need to write down is the last part (hpqthb08.exe) remember, your file may be different than mine which I am using as an example.
3. Go to your start menu, click on settings, and open your control panel.
4. Double click on Administrator Tools
5. Double click on Microsoft .NET Framework 1.1 Wizards shortcut and a window will pop up with 3 options …select “Fix an Application
6. Locate the file you previously wrote down in step 2 and double click on it
7. The wizard should ask you to if you would like to restore the file, click yes and follow the rest of the prompts (I can't remeber them) until it leads you to run the file in “Safe Mode and select that option.
This is all it took to get my Image Zone to run as usual, no more error message. Let me also note that I am running Windows XP and do not have Service Pack 2 installed. I hope it is as easy as this for you to fix this most frustrating and unexplainable problem. Good Luck!!!
