Hello @RICHARD SELTZER,

Thank you for reaching out to us through our Community Forums!

Before continuing, please be aware that Nitro Pro 11 or older are already discontinued as documented in our Sunset Policy: https://www.gonitro.com/support/sunset-policy . With that, support for the discontinued versions are no longer available.  

If you are interested in upgrading your license to Nitro Pro 13 with a discounted rate, kindly access our Upgrade Portal and enter your Nitro Pro 9 serial number: https://www.gonitro.com/pro/upgrade 

You may also want to purchase Nitro VIP Access (formerly Software Assurance) that entitles users to free upgrades for the next release of Nitro Pro and Premium Support for one year after the purchase date. (Premium Support is prioritized ticket support with our Technical Support staff/Nitro Customer Success and Service Team for one year after the purchase date).

You should then receive an email confirmation with a new serial number to activate Nitro Pro 13 and to know more about some enhancements and fixes with Nitro Pro 13, please visit our Release Notes page https://www.gonitro.com/nps/product-details/release-notes 

In addition to that and many other feature improvements, version 13 also contains some important security vulnerabilities fixes that you might want to consider when deciding whether to upgrade to it or not. You can find out more about these fixes here:  https://www.gonitro.com/nps/security/updates 

However if you prefer working with an older version and as a courtesy, we recommend that you repair your Nitro Pro. Please reboot your computer before and after running this repair to ensure that there are no ties to Nitro still active in the background. You may refer to this article: https://kb.gonitro.com/knowledgebase#/search/repair/000004603 

If Modify button is greyed-out, please refer to this screen-cast that will teach you on how to go to Control Panel > All Control Panel Items > Programs and Features and repair your Nitro Pro program or any application installed on your system: https://www.screencast.com/t/rvpUkq40c

Thank you for choosing Nitro and I hope this helps.
