I screwed up. Did disk cleanup and defrag as I regularly do and must have dumped something I normally don't do.
Any feature of HP will no longer open, though the HP "picture" launches.
Behinf the picture a window opens which I can't see or drag.
Another window, for example, Document Viewer will open. I can drag it to view it.
Regardless of the viewer window, it will say the same thing (not the exact words); the feature you are trying to use is on a cd rom or other removeable disk ...
The same deal happens with photos I downloaded from a forum. ( I downloaded them to my newer computer and they open fine).
On my XP PC, if I choose an application like IrfanView it'll say "Can't read file header! Unknown file format or file not found!
If I try to open a photo via HP Image Zone I get "the feature you are trying to use is on a cd rom or other removeable disk ..."
None of my photos will open now.
Even though I have several System Restore dates to choose from, after it runs through restore, restarts the PC, I get a window which includes "system restore incomplete".
Prior to my monthly "cleanup", all was well.
If this is of any help. The pics I download which won't open have the IrfanView logo instead of a thumbnail. Most of those pics are posted by folks via photobucket. I went to photobucket and download 3-4. One of them actually downloaded normally and the others downloaded and wouldn't open as has been described.
Any help will be greatly appreciated.
