cannot install iTunes, Windows 7; error 7
I downloaded the last iTunes update and since then, have not been able to open iTunes. I have followed the instructions from the community posts about uninstalling iTunes and all the ancillary programs several times and still cannot open iTunes. Each time I reinstall, I get an error message about the Apple Mobile Device Support and the install stalls. I cannot get past it. If I hit ignore and let the install finish, I end up with error message iTunes not installed correctly, please reinstall Error 7.
I run Windows 7 on a Toshiba Satellite laptop. All of my Windows updates are current.
Please help. I can't back up my iPhone b/c my settings are for backup on computer. I cannot backup on cloud b/c of this. Because I cannot backup, I have updated my software on the phone yet.
In backup/upgrade limbo.
iPhone 6 Plus, iOS 8.1.2
