Acrobat DC Pro Subscription not working - Failing at INstallation

[vasantha kumarb49447465]

Dear Team,

I'm facing an issue with the installation of DC acrobat Pro after subscribing it . Its been 6 months I'm unable to use the tool after being paid . 

Currently the system shows the version as "Acrobat Reader DC" but Im trying to install Acrobat DC Pro as per my subscription . 

It keeps staying at this page during installation even after 12 hours .

Try it with the installer from here: https://helpx.adobe.com/acrobat/kb/acrobat-dc-downloads.html

Thanks I have tried installing this . BUt I'm unable to sign in and use this Acrobat DC Pro . Attached the error message .

1. It shows Internet connection is down or clock settings is wrong . When I choose "Sign In Later" it throws me with Trial option.

2. It shows to start the "TRIAL" option . I dont know why it has to be a trial when I'm already subscribed 

3. When I Choose option "License Software" it agin shows to retry connecting to Internet or Enter the Serial #
