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

Solution

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.

How would I do this? I cannot find IDEA_JDK_64

[mdo]

IDEA_JDK_64 is an environment variable: for a simple test open a cmd.exe, type "SET IDEA_JDK_64=..." where "..." is the full path to your JDK directory, look at the linked webpage, there is an example that reads "c:\Program Files (x86)\Java\jdk1.7.0_17". Start idea64.exe from within this cmd shell by hand.

Thank you! I just had to use the SETX command in cmd.exe Works perfectly now! Thank you :)
