Windows 7: Can't reinstall Microsoft office home and student 2007

Hello all.

Im having an annoying problem with msoffice today. I notice many of the icons and functions of office begin to not show/work, so i decide to uninstall and reinstall it. But when i went to uninstall it, i got errors, leaving the uninstall incomplete. I ended up using the windows uninstall cleaner or something similar and got rid of it. When it still wasn't gone i found a tut online and removed several registry keys. After that i was pretty sure the program in its entirety would be gone. Now.. when i try to reinstall it, i get the error shown in this picture..

so i did what it asked and gave full permission for that key in regedit. But when i tried to install it again, same error.

i really have no idea what to do next here, i kinda need these programs for school.



it would be wonderful if anyone can offer any ideas.

thanks

Looks like you messed up playing with the registry keys. I assume you have backed up the registry before tampering with them. Just reimport those keys. Else try to set back to an early restore point and start anew.
