APPLICATION HPSU -0004 MISSING FROM LIBRARY
Basically, the HPSU-0004 Error states that one or more DLLs (libraries) needed for the Update utility to run are missing.The
libraries were deleted, or pointers to irrelevant libraries were left in
the Registry.2 Possible Solutions:The EASY solution:1. Remove all of your HP (Hewlett Packard) Printer software from your computer and do a fresh install from the CD that came with your printer.The Hard Solution (only do this if the easy one doesn't work):1. Download a current version of the FULL drivers+applications (single HUGE file) for your printer;2.
Start running the file downloaded in the previous step, until it offers
the option to install the software (other options might be there, such
as "read the Readme file");3. Do NOT click on "Install",
but rather simply exit the Installer (cancel, exit, ...) - the reason
for step 2. above was to just have the downloaded file extract in an
orderly manner all the files that it (and YOU) would use for its (and
YOUR) further processings;4. Locate on on your drive the
installation folder created in step 2., and -- under it - the folder
"setup\hpupdate" (the whole thing should be located somewhere under the
TMP or TEMP folder - just run a Search/Find for it, using your search
engine of choice);5. IF (and only if) you have located the HPUPDATE folder in the previous step (you will, normally), continue:6.
Under Windows Control Panel, start the "Add/Remove Programs" applet,
and -- in the list of applications it presents -- look for "HP Update";7.
Remove the HP Update application as you would any other application
(the uninstall process might end with some errors for files not found -
this is normal in this case, as we already know that some files are
either missing, or mistakenly pointed at, as stated earlier in this
text);8. Now go to the setup\hpupdate folder located in
step 5. above, and run (double-click on) the only *.msi fie found within
it (this will reinstall the version downloaded of the HP Update
utility);9. When Installation (previous step) is
completed, run the newly installed HP-Update utility, to find further
updates both for itself (you might not have had the most recent version)
and for any other HP application that might reside on your drives.10. This completes the processGood Luck!
