I have an HP J4680 all-in-one printer run by an HP Pavilion dv7-1020US computer using Vista. I get an error message on every startup that the path to trayapp.msi is missing. This first started after an uninstall was interrupted by a power failure.
I have read the various fixes on the forum but all seem to involve either uninstalling or reinstalling the software for the printer. When I try to uninstall or install the printer, I get a message that there is already an installation in process that must finish before another one can be done. I get the same message when I try to install any program or update, not just the printer software.
How do I clear the failed installation so I can try to fix the trayapp.msi problem?
Thanks for your help
