No HP devices detected. HP Solutions Center will close now.

Now depending on the operating system.
Tell you how to get this issue resolved but would require some extremely hard work.
First if using the cd right click the cd and single left click on the open button.
once there you will find a folder called util(keep opening the folders until you find a file called l4_uninstall or uninstall_l4 and double click the file).
you will now see a black window.
even though nothing else shows up click on the enter button on the keyboard of your computer and keep on clicking on ok on the uninstall windows.
once all the windows have closed down.
restart the computer
once restarted.
click on the start button on the bottom left hand corner of your computer screen and click on run or press the windows logo button on the keyboard and while pressing it press the R key along with it.
in the run dialog box(the new small window) type in cmd and click on ok or hit the enter key.
in the black window type the following
sc delete hpslpsvc
sc delete hpqddsvc
sc delete hpqcxs08
after all the above are done do the same above and open the run dialog box.
now type services.msc and click ok or hit enter.
and look for any services beginning with the word Hp and double click the option.
now in the new dialog box click the stop button if stop is highlighted,
now under startup type in the same window click on the drop down list and select disabled.
do this for any hp entry seen there.
after that is done x out of the services window.
open up my computer(in vista would be called computer)
now (double click) open the local disk C drive(your drive where windows is installed).
goto the program files and open it.
now select the hp folder and select it by single left clicking it and press the shift button and simultaneously press the delete button , a conformation box would show up asking if you want to delete the folder permanently click on yes.
****note****
if while doing the deleting step you get an error go into the hp folder and delete whatever folders you can.


once that is done click on the back button on the top of the same my computer window and open up the folder called windows( this is while your not inside the hp folder).
now you can search for the folder called twain_32 or if your fast at typing then select any one folder and type tw.... the twain_32 folder should be single right clicked and renamed to old twain_32. Or you can select the file and press the f2 button on your keyboard for renaming.

after this is done
press the windows key and the R button once again to open the run dialog box.
once this is done type the word regedit and click on ok.
the new window opens (be very careful and read very carefully what I write now)
click on the plus sign before hkey_current config.
now click on the plus sign that says system,then expand current control set
Expand the control header and expand the print header.
once done any printers that you are not using please select and press the delete button and click on ok on the dialog box that will popup once you press delete.

now don't close this window we need to now goto hkey_LOCAL MACHINE
EXPAND TILL YOU GET SOFTWARE WHICH YOU ALSO NEED TO EXPAND.
NOW LOOK FOR THE HEWLETT PACKARD FOLDER (NOT HP) and select it and delete it.

restart your computer and goto the link or you can copy and paste the link below in the address bar of your browser and hit the enter key
http://get.adobe.com/flashplayer/?promoi...

click on the download now button and look for any information bar towards the tabs of your explorer.
click on the information bar and click on install.
if the above doesn't happen don't worry proceed to the next step.

restart the computer one last time and dowload the software from hp.com
(look for support and drivers,click on download software and for product type in "c7280"
or watever your product is.

once the software has been downloaded install the software now if you have the same problem again I would recommend calling 1800-474-6836 and getting help because it just might be a computer issue (your operating system).
