Hi Deepa,

We do not support outdated versions of P21 Validator. If you installed version 3.1.2, during your first start it will be automatically updated to the latest version (4.0.1 as of today). In this way, we ensure that you are in sync with validation utilized by FDA and PMDA.

Note that version of Engine is responsible for validation results. Version of application does not have impact.

Kind Regards,  
Sergiy

Hello P21 Team - Could some one please suggest where is the link to download P21 version 3.1.2?

I could not find it. The only version that available on downloads is P21 version 4.

Please advice.

Thanks,  
Deepa
