All browsers do not see Java JRE at Windows 8.1

I am unable to run any Java applet in all browsers. Internet pages containing applets (or like that) says like «JRE is not installed on your machine. Install JRE and retry» or they just shows nothing. Here is a fresh Windows 8.1 x64 for single language. There is none administrative politics I believe because I installed it personally. I turned off Windows firewall and Defener’s real-time protection. Then installed jre-8u77-windows-x64.exe :

C:\Program Files\Java\jre1.8.0_77\bin>java.exe -version java version "1.8.0_77" Java(TM) SE Runtime Environment (build 1.8.0_77-b03) Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode) 

enter image description here

Java is enabled in browsers: Now I’m verifying if Java installed with https://www.java.com/en/download/installed.jsp . Firefox 45.0.2 — No Java presented at the Plugins page about:addons . At Java.com I press «Agree and continue». Next, I’m told «Java is disabled or not installed». Chrome 49.0.2623.112 m — There is no Java listed at chrome://plugins/ . Java.com says «The Chrome browser does not support NPAPI plug-ins and therefore will not run all Java content. Switch to a different browser (Firefox, Internet Explorer or Safari on Mac) to run the Java plug-in.» IE 11 (updated automatically) — At Java.com I press «Agree and continue». The applet does not appear. P.S. I tried to instal JRE 7 also
