Pls advise how to again be able to install programs like Office 2010 and iTunes; which started failing a month ago in windows7, and the upgrade to windows 10 hasn't helped. I hate to throw this laptop away, but it's useless without itunes and office. It did install all windows updates done yesterday just before upgrading to windows 10. it seemed to install 10 upgrade without a problem.

- windows installer service lets me start it, but it's greyed out so cannot change Manual to Automatic under Properties.
- search cannot find any .msi files; itunes6464.msi, e.g.
- installing itunes and office, failure shows 'the network resource with the msi file cannot be found. select another pathway.'
- already uninstalled every Apple program/folder, then tried install.
- This laptop given to me by employer as it was obsolete; the 7 OS Key isn't recognized by microsoft as authentic, so cannot do clean install. i've tried the Key on underside on the Asus tag; i've also tried a different key found by Belarc on the OS; neither are recognized by microsoft. Maybe my employer quit a subscription or something...
- Windows Repair useless. rollback to restore point doesn't work; that feature has never worked for me on any device, ever.
- my system specs are in my profile
