JRE issue with getting Spring Tool Suite installed

Question

I downloaded Spring Toolset 3.6 from here:

https://spring.io/tools/sts/all

Unzipped it, launched sts.exe and got this error:

---------------------------
STS
---------------------------
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run STS. No Java virtual machine
was found after searching the following locations:
D:\Setup\spring36\sts-bundle\sts-3.6.3.RELEASE\jre\bin\javaw.exe
javaw.exe in your current PATH
---------------------------
OK   
---------------------------

I have following version of (32 bit) java

C:\Users\Chad>java.exe -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode, sharing)

I tried adding the following 2 lines to the top of the STS.ini:

-vm
C:\Windows\SysWOW64\javaw.exe

and got this error:

---------------------------

Tried adding an Env variable:

JAVA_HOME = C:\Windows\SysWOW64\

...same error

when I opened up the Java Control panel, I saw that the active version, 1.7 pointed to this path:

C:\Program Files (x86)\Java\jre7\bin\javaw.exe

I also tried adding the following to my PATH variable

C:\Program Files (x86)\Java\jre7\bin

...no change,

When I noticed the following line in one of the error messages above:

Dosgi.requiredJavaVersion=1.6

I tried switching the active version of java (the one checked inh the control panel) to the 1.65 version and I changed all of the above paths to point to reference it.

C:\Program Files (x86)\Java\jre6\bin\javaw.exe

I'm sure I didn't try all permutations, but I am obviously gasping at straws.

I also tried downloading the 32 bit JDK because I saw something about maybe needing that.

Is this some sort of a 32/64 bit mix up? The STS zip file was named indicating a 32 bit version, although at work on my laptop I somewhere found a version that had both 32 and 64 in the name of the zip. I only saw one version of the app in the zip file. How can one app be both 32 and 64 bit at the same time?

spring-tool-suite-3.6.3.RELEASE-e4.4.1-win32.zip

This is my first attempt to try anything using Java and I'm frustrated just starting...

Answer 1

I had this problem with STS4. Solved it adding -vm parameter in SpringToolSuite4.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.5.100.v20180827-1352.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.800.v20180827-1352
-product
org.springframework.boot.ide.branding.sts4
--launcher.defaultAction
openFile
-vm
C:\Program Files\Java\jdk1.8.0_162\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.8
--add-modules=ALL-SYSTEM
-Xms40m
-Xmx1200m

IMPORTANT: this didn't work when I added the config parameter at the end of the file, it had to be in the middle between openFile and -vmargs lines.
