Attempting a STS v2.8.0 installation on a Win7Enterprise 64 bit environment with Admin privileges. Both the 32 bit and 64 bit installers pop a "Installer - SpringSource Tool Suite" dialog saying:
"This application requires a Java Runtime Environment 1.5.0"
I'm currently using STS v2.7.1 with 32 bit jdk 1.6._20 without issues.
I have attempted the STS v2.8.0 installation with 64 bit jdk visible to the environment with the same results.
