nlssvc32.exe file is missing


Recommended Posts


  I've tried to repair NitroPro 11 and got the message that "something is preventing the licensing service"....I am unable to repair or uninstall my current version of NitroPro.  At the same time, I am unable to upgrade to NitroPro 12.  I've done some research and finally found that my nlssvc32.exe has gone missing - overnight.....no updates to Windows that I could find..... HELP!!

Hello @CleanTech92058 ,

Thank you for posting on our Community Forums!

Please use the tool I have provided below to remove all files associated with Nitro Pro and reboot your system.


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: http://kb.gonitro.com/knowledgebase#/search/stamps/000001671

When your system is back up, close all of your open applications and install Nitro Pro 11 ( from the page I have provided below:


I hope this helps!

Thank you for your response.  We are unable to uninstall after running the tool.  It says "something is preventing NItro from running"  ...or s.th. similar.

Also, we have sinced upgraded NItroPro 12 - the only option to have NItro operated  (  :(  ).    NItro Pro 11 is still on PC.
