Question

Good day.

I decided to learn Java. I installed JDK and downloaded eclipse-java-helios-SR1-win32 for windows 7.

But i can’t launch eclipse because i always receive the message:

Error: couldn't find Java SE Runtime Environment

I tried to reinstall the JDK but installer gave me such message:

Error 1723, There is a problem with this Windows Installer package.
A DLL required for this install to complete couldn't be run."

At least here is information that eclipse gave to me:

Java was started but returned exit code=2 

C:\Windows\system32\javaw.exe
-Dosgi.requiredJavaVersion =1.5 -Xms40m
-Xmx334m
-XX:MaxPermSize=256m
-jar C:\eclipse\plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
-os Win32
-ws Win32
-arch x86
-showsplash
-launcher C:\eclipse\eclipse.exe
-name Eclipse
--launcher.library

-Xmx384m
-XX:MaxPermSize=256m
-jar C:\eclipse\plugins/org.eclipse.equinox.launcher_1.1.0.v20100507jar

Here is a picture of the error. I suppose that i could make few mistakes in the log.

Change your eclipse.ini (right beside the eclipse.exe) in order to:

• specify a full JVM path (-vm argument: -vm C:/Prog/Java/jdk1.6.0_21/jre/bin/server/jvm.dll for instance). Don’t use the one in C:\Windows\System32.
• not specify the jar used for the launcher.library

See this eclipse.ini as an example.
