Apologies for the delay in replying. All previous posts related to our continuing use of Windows XP and I see the cross-references are also similarly dated. So it all pre-dated Windows64...
Our Windows 10 laptop has just returned from Scandi so I've checked the contents of SysWOW64 and - just to confuse the issue - it has Expsrv.dll, but neither of the ones you mention. Curses.
However, having just re-read all our posts, and the cross-references, I'm inclined to conclude that variants of Exsrv, Exsrv2 and Espsrv are most likely different names for the same module group at the heart of the different symptoms. So we still feel trial-and-error is the way to go, see below.
As for CCleaner, we all use the freebie variant. However, your v4.08 is well out of date so I do recommend you update to the current v5.16xxxx and set it to alert you of further updates automatically.
As for the clash with Kapersky, we've downloaded and used CCleaner from FileHippo. com, on numerous machines and for many years, without the slightest hiccup. So is it possible to configure Kapersky to 'accept' CCleaner? Failing that, and provided you first make a System Restore point, I would have thought it reasonably safe to temporarily disable Kapersky, download and install CCleaner, re-enable Kapersky and then do a virus check to see what happens.
If all goes well, then I would suggest removing ExSrv.dll and ExSRV2 from SysWOW64 on your AMD/W7 machine and see what effect that has. Namely does VirtualRPC start up? And are there any adverse symptoms with other applications? Then if need be, you could try copying across the 2013 version(s) from the i5/W8 computer to see what happens. I'm sure you get the gist.
E&OE, good luck, fingers crossed, Mike N
