SAP NetWeaver 7.0 Java Trial Version Installation

Greetings

I have downloaded the SAP NetWeaver 7.0 Java Trial Version from the web site ([https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/webcontent/uuid/a62ad7fa-0a01-0010-3489-f3fc32658bd8] [original link is broken];

downloaded all 2 files - Developer Workplace 7.0 SP14SR3 Java Server Evaluation and Developer Studio 7.0 SP14SR3 Java Server Evaluation)

Verified that all pre-req are available and installed.

When executing the installation (sapinst.exe in the IM_WINDOWS_I386 directory) all goes fine, until you get to the Define Parameters section.

The wizard request to specify the path for "Developer Workplace NW 7.0 SR3", but any path that I specify, return an error stating that I need to specify the path with the correct label.asc.

(looking for a label.asc with the following prefix - SAP:DW-UT:NW04SSR3)

Any assistance where this is and why this is not part of the two files above?

Thanks
