We have two Windows 7 systems. Internet Explorer 9 installed effortlessly on the 64-bit machine, but the Dell 32-bit refuses to install, linking to an error page that gives 4 recommendations, all of which either were already implemented or have been tried to no avail.
I have as yet to see any answers online to this issue.
I think it has to do with being a “Trusted Installer” on systems sold by Dell, since I ran into that on other issues, but that is only a pure guess.
Please let me know if you have input beyond the Dell support response.
