Hello @Johnny Chin,

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

For the sake of initial troubleshooting of this issue, 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 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

If repairing didn't help, let us uninstall using our Clean-up Utility then reinstall by referring to these steps:

1. Download and run our Clean Up utility to uninstall your current Nitro Pro and reboot your machine:

NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: https://kb.gonitro.com/knowledgebase#/search/stamps/000004509. Clear all your Downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

2. Download and install Nitro Pro 12.16.9.574 x64-bit MSI installer http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi

Important:  If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. In order to bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

3. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 23460x-xxxxxx-316004

If all fails, we highly recommend upgrading to our latest version, Nitro PDF Pro 13, which comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. To upgrade to Nitro PDF Pro 13, please visit our Upgrade page https://www.gonitro.com/pro/upgrade

Thank you for choosing Nitro and I hope this helps.
