Nitro Pro 11 won't open in Windows 10

[Bill Samuel]

Nitro Pro 11 will not open on my Windows 10 PC. It gets an error message:

The application was unable to start correctly (0xc000007b). Click OK to close the application.

I used Control Panel to do a Repair on Nitro Pro. but that did not help.

Hi @Bill Samuel,

Thanks for posting on our community forums!

Let's do a fresh install with the help of our cleanup tool:

1.    Reboot your computer.

2.    Close down any applications that open automatically.

3.    Unzip the following
file: http://install.nitropdf.com/support/downloads/cleanup.zip

4.    Copy the .vbs script to any local spot on your machine such as your
Desktop.

5.    Double-click the file to run/execute the script.

6.    Reboot your computer once more.

7.    Download and Install Nitro Pro 11 using this link: https://www.gonitro.com/product/downloads 

8.    Make sure your copy is activated: http://kb.gonitro.com/knowledgebase#/search/activate/000001639

I hope this helps.

OK. This worked. And it activated automatically without me having to do anything. The process reminded me I have done this before, as I overwrote my prior copy of cleanup.zip. Properly functioning software would not require uninstalling and reinstalling all the time. I don't have to do this with other software I have.

And it worked for one-time use. Now I try to make a PDF document, and I get an Unknown Error.

Your software is crap. It should not be allowed to be sold it is so defective. It will only work briefly, and then with long delays.

I am going to request a refund from sales. It's criminal that you actually take money for something so defective.

Hi @Bill Samuel,

Thank you for the update and I apologize for any inconvenience. 

There are a number of reasons why an Unknown Error message would show up. I've sent a response to your support ticket. Let's continue our conversation there so we can ask for the PDF document you are working on and further troubleshoot.

I hope we can sort this out soon and I appreciate your patience.
