So setting up a new machine, I tried adding the Google search provider plugin for IE11; I wanted to add Google as my default provider rather than Bing. However, the Add-On kept failing to install:
The search provider could not be installed.
This might have happened because:
- A required file could not be downloaded
- The website is unavailable
- You are not connected to the internet
You might want to try again later.
Great. The problem was repeatable, and continued after reboot, and reset of IE’s settings. In desperation, I tried change the country that I was in (in the top right)…
I changed from United States to Turkey and back – and when I tried to add the extension, it installed without problem.
Hardly conclusive, but an interesting result nonetheless. Let me know if it works for anyone else!
