Discussion Board for collaboration on Qlik NPrinting.
I have just installed qlik nprinting server June 19 and installation was completed successfully without any error.
But when i was trying to open nprinting web console . It is displaying an error as below :
Error trying to open the page.
Also , my qlik nprinting web engine service and qlik nprinting scheduler service is getting stopped automatically after few secs.
When i checked the logs i found below mentioned error:
Web Engine client certificate not found in store. Generating a new certificate from RabbitMQ CA key
Qlik.NPrinting.WebEngine 220.127.116.11 Qlik.NPrinting.WebEngine.WebEngineWindowsService 20190820T040417.746+05:30

Thanks in advance.
Did you perform database restore after upgrading?
If you did upgrade from another NP 17 + server and no restore was done, please check the following article which mentions how to solve the issue.
If this was not an upgrade and a fresh installation, can you tell us if you ever had any other version of NPrinting installed on this computer at one time or another?
This is not an upgrade. I have done a fresh installation.
But yes earlier i have nprinting version 17.x install in the same machine.
I uninstall earlier version i.e. 17.x and then tried to install the new version
If this is fresh install, then do the following to clean up the previous install.
NOTE follow the steps in the correct order below or the uninstall process will not work normally.
Next, open the following and rename these folders:
NOTE: if you not able to rename the folders, restart the server and try to re-name again.
Once you are able to rename the folders, Install NPrinting server once again but make sure that you have met all system and user account requirements before proceeding.
If this does not solve the issue, please start a support case so we can assist you further to clean up your machine in further detail before attempting another re-installation.
I think you uninstalled only the old Version of Qlik NPrinting Server, Engine and Designer but you still have RabbitMQ installed. Please remove also it, reboot and install June 2019.
You are experiencing a bug solver in April 2019 by upgrading the Qlik NPrinting Messaging service but for some reasons it seems that in your computer the old version is still in use.
First of all thanks for providing such a detailed explanation.
I have followed all the steps shared by you but now my installation is not getting completed.
Please find below the image where it is struck.
Thanks in advance.

From only this screenshot it is not possible to understand what is happening. We need to check at least the logs you find in the folder C:\Users\NameOfTheUserWhoInstalledNprinting\AppData\Local\Temp and logs from https://help.qlik.com/en-US/nprinting/June2019/Content/NPrinting/AdministeringQVNprinting/Logging.ht...
