Qliksense 3.0 SR2 desktop

[markp201]

Our junior developer decided to install june 2018 desktop but our server is v3.0 SR2

He's getting compatibility issues when porting his local work to the server.  

We need to get him back on the version but when I checked the support portal, I can

only see back to June 2017.  How can we restore the desktop to 3.0 SR2 ?

Thanks
