Marcos, did you reply to my last about activation, or the earlier response about EIS install?

So we move on, I managed to install EIS, and then install ESS over that, however it will neither activate nor permit "change license". I considered that anti-theft may be involved in this, however anti-theft log on is met with an HTTP 400 error, not a valid WS-Federation protocol message, so for now I am stuck.

See above, I downloaded the installer having fully removed 10.0 from my Win10 machine as instructed, how do I now install 10.1 if the installer won't run?

It seems life only gets more interesting. I fully uninstalled 10.0 and downloaded the 10.1 installer, rebooted the machine and ran the installer (with the logger enabled) however the installer insists that I already have a current version installed, and of course terminates. Next?

Thanks again, this is in hand. Meanwhile my win 7 machine updated to 10.0.390 a few days ago, and now has exactly the same problem! I suspect you may have a more serious problem here. I have to admit that given what I pay for ESS, this is getting very annoying.

Apologies for the long gap, I've not been around! The ELC log is here: https://drive.google.com/open?id=0B-TCEAaaeomiLWYtYU1BaWZrbkU Thanks

Ok, I've been going around this now for 2 days. Windows 10 version 1607 Eset SS early V10, home page warns me my virus signature is OOD Update page says it is up to date! So update just check and says it is not necessary. So I have tried clearing the cache, rebooting and updating to no effect. So I completely uninstalled the software, rebooted, downloaded and installed V10.1.204 Now I get exactly the same result! Cleared the cache, rebooted, no change. Last update remained 27/06/2017 both before and after reload of software. Signature version reported before was 14855, now it is 15061, which is very strange given that both versions report the same date. Incidentally my Win 7 machine running 10.0.390, reports signature version 14855, last update today, 11/7/2017 Any thoughts anyone?
