Nitro PDF Pro 13 slow on startup

[Bradley Schwedhelm]

Good day,

I have the same issue with my version. When I start up, it loads very slowly.

When I click print, the entire software freezes until the document has concluded printing.

Could someone look into it or is there an update?

Version: 13.70.7.60

Serial: 504906-uvwxyz-089514

Hello @Bradley Schwedhelm,

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

As part of our initial troubleshooting, kindly refer to these steps:

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

2. After rebooting, download and install the latest version of Visual Studio (vc_redist.x64.exe & vc_redist.x86.exe) then reboot again your machine. Visual Studio 2015, 2017, 2019, and 2022 all share the same redistributable files:

3. 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.

4. Download and install Nitro PDF Pro 13.70 using these installers:

x64   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x64.msi
x32   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x86.msi 

To know if you have a 32-bit or 64-bit Windows system, please refer to this article:

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"

5. After installation, you can activate it by opening Nitro PDF Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number.

6. Turning off User Account Control (UAC) for Nitro Pro. Here are two methods that you can follow:

   a. Right-click the Nitro shortcut > Properties > Compatibility > Turn off any settings there.

   b. 
      i. Right-click > Troubleshoot Compatibility > Troubleshoot Program
      ii. Check "The program requires additional permissions" > Next > Test the program...
      iii. Wait for the program to launch > Next > Yes, save these settings for this program > Close

Thank you very much in advance and I am looking forward to hearing back from you.
