mattoyol91 0 Posted November 25, 2015 Share Posted November 25, 2015 I also experienced the same issue as him. I tried to activate ESET as trial and failed and the error code is 4099. My OS is Windows 10 64bit (Build 10240). Link to comment Share on other sites More sharing options...

Administrators Marcos 5,277 Posted November 25, 2015 Administrators Share Posted November 25, 2015 Error 4099 should occur if there's a problem with verifying certificate chain. We've made some improvements to mitigate these issues which will be included in the upcoming service build of v9 soon. In the mean time, you can install v8 which has all protection features of v9 except Banking and Payment Protection. Link to comment Share on other sites More sharing options...
