Hello, I have inherited a project that i believe was created using V7.0 Libraries. 

When i compile my charts im getting an error

E: Necessary files are missing for block CH_AI. Please note that you have to install exactly the same version of the library as the one this block was imported from.

This is exact issue is described in the forum post:

Necessary files are missing for block CH_AI - 96481 - Industry Support Siemens

I currently have PCS 7 AP Library V71, PCS 7 AP Library V81, PCS 7 Basis Library V71 and PCS 7 Basis Library V82 installed.

I can see in the blocks list that the CH_AI block (FC275) has an author "DRIVER70". Leading me to believe i need the V7.0 Libraries. 

V7.0 is not available at the below link only V7.1 and above. Where can i find the V7.0 Libraries?

SIMATIC PCS 7 Libraries Updates - ID: 109480136 - Industry Support Siemens

I also dont have the physical disk. 

 Thanks for the response, i have opened a support ticket. In the mean time i would like to attempt migration to the PCS 7 AP/Basis Libraries V7.1. Do you know of any resources that might help me do this? I'm not working with a live plant, the projects im working with are completely PC simulation based and consist of a single CPU and OS.
