Updated from SAPGUI 7.3 rev2 to SAPGUI 7.3 rev3. When I start SAPGUI Rev3 I get the following error: Failed to find JRE/JDK version 1.7+ (64-bit).
I also still have rev2 on my machine and it starts without any issues. This is on a Mac OSX and I have the Oracle Java installed (1.7 Update 25).
Help! :-)
