Unable to launch Nitro Pro 12 after installation


Recommended Posts

Hello guys,

We just bought a bunch a Nitro Pro 12 licenses but on a computer we are unable to launch Nitro just after the installation. It happened only on one computer that has the same configuration has the other one.

- Antivirus

- Operating System


After investiguation I saw that the Nalpeiron Licensing service was set to automatic in Windows but not running event if I try to launch it manualy it says

"Nalpeiron licensing service could not start error 1722 the RPC server is unavailable"


This service is running on all of our computer where Nitro is running well. So I tried to disable Antivirus/firewall and install with local admin rights but it still the same....

I also tried the nitro tools to clean all registry keys etc.. and another tool to repair Nalpeiron Licensing service but the same...


Does someone has any idea of what we can still try to have Nitro Pro working on this computer ?


Thank you.

I found a post that tells :

4. If it will not start and you see an error, 1717 or 1722, scroll down to Windows Event Log in the 'Services' dialogue box > Right-click > Properties. Set it to 'Automatic' and click Start.


I also tried to start this service with local admin privileges but it says access denied service cannot be launched on a local computer.


Please help me.

Hello @Leslie V.,


We found that the Nalpeiron Service cannot launch due that Windows Log Event service was not running and doesn't want to start.


After lot of investiguation on Microsoft Technet I finally found how to resolve our issue.

Let's see below what we done :

Delete all files under C:Windows\System32\winevt\Logs  (Backup to log.backup folder)

- Reboot

Then the Microsoft Log Event and Nalpeiron service were running and I was able to launch and activate Nitro !


Wish that it will be usefull for other people using Nitro Pro.

Hello @Clyde B,

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

Kindly try this location instead: C:\Windows\System32\winevt\Logs

A '\' is missing after ':' symbol.

Thanks for choosing Nitro Pro and I hope this helps!
