intellijidea无法创建JVM错误代码-1

我有intellij-idea安装.虽然我已经设置了JAVA_HOME环境变量,引用了"C:\ Program Files\Java\jdk1.8.0_45"但是当我尝试运行它时,我最终得到以下错误:

failed to create JVM: error code -1. JVM path: "C:\Program Files\JetBrains\IntelliJ IDEA 2017.2.2\jre64\" if you have a 64-bit jdk installed, define a JAVA_HOME variable in Computer> system variables> system settings> environment variables.
