Hi,
I am also a long time user of CCleaner, first on my old XP, now on my newer device.
I run Windows 7 Professional Service Pack 1.
My Internet Explorer is version 11.0.9600.18537
And CCleaner hangs when cleaning IE.
I have updated a few times, but the hang problem persists.
So I revert to CCleaner Free 5.22.5724 (64-bit), which is the last one that works for me.
I think it is about time we knew which version of IE is compatible with your wonderful software.
Thank you.
