Nitro Pro 13 (x64) keeps relaunching after being closed since 13.15 update

[RogerKaplan 0]

Since I installed the update to 13.15 yesterday, every time I close the program, it relaunches on its own about 5 seconds later.  Sometimes will do so 2 or 3 times before finally staying closed.

I tried repairing the install, and I tried completely uninstalling and re-installing.  No change.

Hello @RogerKaplan,

Thank you for reaching out to us through our Community Forums and sincere apologies for this inconvenience.

Did you uninstall completely through Control Panel \ Programs \ Programs and Features?

If yes, let us try some troubleshooting by referring to these steps:

1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. Kindly note Appdata folder is hidden and to unhide it, please refer to this article https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/ 

2. Download and run our Clean Up utility to uninstall your Nitro Pro: http://install.nitropdf.com/professional_13151282/install-cleanup/install-cleanup.zip 

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/000004307 

3. Please 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 Pro 13.15 using below offline installers:

x32 http://install.nitropdf.com/professional_13151282/en/retail/nitro_pro13_ba_x86.msi
x64 http://install.nitropdf.com/professional_13151282/en/retail/nitro_pro13_ba_x64.msi

If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790 

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number.
 
Thank you very much in advance and I am looking forward to hearing back from you.

Did all those steps to the letter, but still have the same problem.

I had the same problem.  I followed the directions above and so far it has not reoccurred.  Since the reinstall I have not tried to login into my account within the app.  I was having problems with staying logged in with the previous version.  Not sure if that could be the problem but I don't really see any benefit for me so as long as this problem doesn't reoccur I'll stay logged out.
