我想在Windows 8.1 x64上運行類型安全激活器。它口口聲聲說我沒有一個有效的JDK安裝:Typesafe activator:Java JDK無法找到
A Java JDK is not installed or can't be found.
JAVA_HOME = "C:\Program Files\Java\jdk1.7.0_45\bin"
Please go to
http://www.oracle.com/technetwork/java/javase/downloads/index.html
and download a valid Java JDK and install before running Activator.
If you think this message is in error, please check
your environment variables to see if "java.exe" and "javac.exe" are
available via JAVA_HOME or PATH.
Press any key to continue . . .
我有我的JAVA_HOME設置爲:
C:\Program Files\Java\jdk1.7.0_45\bin
這是一個有效的位置。
