I tried a manual 64 bit installer via Download Internet Explorer 11 (64-Bit) from Official Microsoft Download Center and it told me installation was successful, restart computer. I restart, and I open IE>help>about, it says I still have IE10 My logs tell me I have 1021 errors, all being CSI missing development keys. Anyway to fix this? My CBS folder was really large, so I told the CBSpersist files out.
