Firstly, thanks for your suggestion. I appreciate it.
Secondly, sorry it took so long to get back to you. The computer is my wife's and she been quite busy with it so I haven't had the chance to test out your suggestion.
Unfortunately, your suggestion didn't work. I tried it multiple times with no luck.
Here's some additional data.
(1) As for the "ReadMe" issue (mentioned in the initial message), the "autorun.infla..." issue looks like the first "%" in the "%lang%" string is in fact the name of the file "autorun.inf". So when "%lang%" is being printed, "autorun.inf" is being substituted for the first "%", hence "autorun.infla...".
Not sure if that helps.
(2) I tried running HP Print and Scan Doctor and I saw something unusual. The initial page shows the following:
Product Connect Software Status
Prem C410,192.168.1.7 Network(192.168.1.5) Installed
Prem C410,192.168.1.7 Network(192.168.1.7) Installed
There is ony 1 printer hooked to the network. I searched through the registry and I did find instances of "192.168.1.5" and "192.168.1.7".
(3) I also tried using the various uninstallers under util\ccc.
L1: Completed with no issues.
L2: On step 10/12, a popup window indicates "Hp Installer Uninstaller has stopped working". I click "Close Program" and that's the end of the processing.
L3: Same as L2. But, after closing the program, a pop-up window asks "Are you sure you want to remove from your computer?" (FYI - No, I did not miss anything here. That is exactly as it is printed. There seems to be 2 spaces between "remove" and "your" as if a filename or program name should go here.) I click "Yes", eventually the screen indicates 100% complete and I click "OK". This sequence happens 3 more times (pop-up followed by a 100% complete screen). After the 4th time, a screen indicates the process is complete, I hit "Finish" and the computer automatically reboots.
L4: Exactly the same as L3.
At times when step 10/12 failed, the "Current Progress" will be stopped on "Software\Wow6432\Hewlett-Packard\" followed by other registry entries. I've searched through the registry and I can find only one entry that matches this: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432\Hewlett-Packard. But, none of the entries that follow that on the "Current Progress" bar match any entries. (Ex: Software\Wow6432\Hewlett-Packard\DigitalImaging\CUE Settings. This key does not exist. There is a HKEY_CURRENT_USER\Software\Hewlett-Packard\DigitalImaging\CUE Settings, but not one tagged with the "Wow6432" entry.
Anyway, it looks like something has gone wrong with this computer's registry. I reluctant to start hacking away at the registry.
I could use some more suggestions.
Thanks!
