Error with sapinstgui.exe

Hi Experts, I just installed the Sa_NetWeaver Trial 7.2 and when I try to install the GUI (C:\Users\rafa\Desktop\NWASABAPTRIAL70206\SAP_NetWeaver_702e_Installation_Master\IM_WINDOWS_I386\sapinstgui.exe)

I get this error

Then I downloaded the JCE from this link http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

create the variable and put the JCE (without unzip) in the path C:\Users\rafa\AppData\Local\Temp\sapinst_exe.5124.1408849963\\jre\bin\ and run the sapinstgui.exe

now I get this error

Could someone help me with this? I'm really confused

Thanks in advance
