I recently installed 64-bit Java and now Eclipse will not start up even though I am using the 64-bit Helios package. Does that mean I need to go back to the 32-bit package?

I get this error dialog as below:

What do you get running:

java -version

on the command line? On Windows with the 32-bit Java I get:

java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing)

With the 64-bit Java I get:

java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.0-b11, mixed mode)

If you have both the 32-bit and 64-bit JREs installed you may need
to specify the correct one to the Eclipse launcher, e.g.:

eclipse -vm <JAVA_HOME>\bin\javaw.exe

You may also configure that in the corresponding "eclipse.ini" file.
