Error launching idea64.exe

Question

When I try to open idea64.exe (IntelliJ IDEA 64-bit version) I get the error "No JVM installation found. Please reinstall the product or install the JDK."

Why is this? I have both Java 8 Update 5 (64-bit) and Java SE Development Kit 8 Update 5 (64-bit) installed. Also, idea.exe (32-bit) works fine

Answer 1

According to JetBrains, idea64.exe uses this JDK search sequence:

IDEA_JDK_64 environment variable
..\jre64 directory
system Registry
JDK_HOME environment variable
JAVA_HOME environment variable

If IDEA fails to auto-detect your JDK, try to set IDEA_JDK_64.
