Can you share more details regarding the use case for older versions of AD engines? You may want to open a shipping request on eSupport for more details. However, it is not guaranteed older AD versions are available to download.
We have 5.13 installed in our PROD environment and want to install 5.14 (in IDQ 10.2 HF2).
I want to run test on my machine (Windows) on a set of addresses with both versions to check the differences.
If you are looking for standalone AD software library for 5.14 version,this is available in Data Quality Center site:
You can login with your DQC ID and download the tool from download Manager>Other Downloads>Archive>Choose your version and platform.
I'll keep this useful info. Got what I wanted.
