IE11 Won't install, no error code!

I'll be honest here and say that I have no idea what your problem is caused by.
However, the DeepClean.log file contains the following errors...

 Line 5661: 2015-05-27 15:01:57, Info                  CBS    Failed finalizing changes [HRESULT = 0x8007371b - ERROR_SXS_TRANSACTION_CLOSURE_INCOMPLETE]

Whether this is related, I don't know.

This error appears to result from an older versiov of the Windows Update Agent...

Errors such as this are difficult to pin down, and historically, are most likely to be solved by a repair install.

Thanks Noel - looks like I may have to do a repair install. Whilst I backup my system regularly, I've been trying to avoid this. Am I correct in thinking that a repair install will leave all my programs and anything installed, plus saved docs and photos etc. intact? Just saves me having to copy them all back over :s

As always, the advice must be to back up your data to external media before attempting anything so far-reaching!

Yes, your programs and data will generally be preserved - a couple of settings may revert back to default, but should be readily correctible.
