Integrate HMI MP277 10" Touch TIA project with Step 7 5.x PLC

[ggg315]

I have HMI MP277 10" Touch and need to connect it with a S7-300 PLC on via Profibus communication - I am using TIA Portal V13 and tried to use the Device Proxy because the PLC program is in Step7 v5.x

- When i tried to initialize the PLC proxy TIA portal V13 unable to select blocks
Also I am unable to download any project to the HMI I have to use Pack&Go to transfer any project to HMI
and when i tried to install Wincc Flexible 2008 SP5 on Windows 10 PC- it gives me error SQL Server 2014 Express Edition failed to install.
