I am in the process of installing the trial of Netweaver 7.0.1 on a W2K3 Server. The SAP install worked ok.

However when execute sapinstgui by double clicking on it in Windows Explorer, I receive the message

Program is starting... Please wait!

Path: C:\DOCUME1\WCASTL1.PMG\LOCALS~1\Temp\1\sapinst_exe.3252.1252024215

For the requested processing mode java policy

files within the used SAP JVM are needed.

Specify the environment variable JCE_POLICY_ZIP and restart.

Since I know very little about installing SAP, can someone explain what I need to do in plain and simple language?
