I've lost my Nitro Pro version 9, I have the serial number. Can I download Pro 9 again?
Luckily, the developers still offer the possibility to download a previous version of the software. I've checked the website and you can download the software in 32 or 64bit architecture mode.
Use the following link to save the installation package to your desktop: https://www.gonitro.com/support/downloads
Here are the direct download URLs, just to make it easier:
