Job done!
I ran again the file "AIO_CDB_NonNet_Full_Win_WW_130_141.exe" and chose "Uninstall".
While uninstalling, an error occurred. I followed the alternative steps and reached the end of the uninstallation process.
Then, went to Control Panel > Uninstall a Program and uninstalled what was left of the HP stuff.
Further, went to C:\Users\..\AppData\Local\Temp and wiped out the 7z... folder.
I ran once again the file "AIO_CDB_NonNet_Full_Win_WW_130_141.exe" and IT WORKED!!!
I have the strange feeling I have done all this before with no result!
Many thanks from Portugal!
