Windows 10: NSIS Error popping up for seemingly no reason?

I keep getting an error saying "NSIS Error - Failed to launch installer." Now, here's the part that's got me really confused. I don't have any 'installer' to speak of. I'm not even trying to install any software at all. It just keeps popping up for no reason whatsoever. It doesn't really impact functionality on my PC or anything, it's just really annoying and grating. I thought at first that its possible that I had a virus, but I did a virus scan and nothing showed up. I've searched anywhere for some sort of software or file I might've tried to install at one point but found nothing. I haven't

NSIS Error pops with no installation going on

Hi there!

For some unknown reason I've recently started getting the NSIS Error pop-up on my Lenovo laptop. From what I've read it's connected to a broken/unfinished installation issue, but the thing is - I've not installed any new program in forever. I've checked for viruses, updated anything that needed updating, cleaned out my downloads and history and the error still pops up.

Is there anything I can do to stop that? Thanks in advance.

 

NSIS Error - STILL not working.

Hi James,

Welcome to Microsoft Community and we appreciate your interest in Windows 10.

I will definitely assist you.

There could be a software installation problem while you are trying to install software with the NSIS installer. If the NSIS cannot install something, the error which occurs could be due to several reasons. For example, improper configuration settings,
corrupted installation files, firewalls, viruses, etc. It could also be a NSIS installer issue where the source program to be installed does not have a complete control over the software.

NSIS errors usually occur under one of the following conditions:

• 
  Software files downloaded from the Internet are not complete.
  
• 
  Downloaded software files have been modified from the original version.
  
• 
  The computer is infected with a virus/malware.
  
• 
  Physical media being used to install the program is damaged.
  
• 
  Required hardware (For example, CD/DVD drive) is malfunctioning.
  

I appreciate the steps you have performed. Let’s try simple steps and check if this helps in resolving the issue.

Step 1.

Try to rename the downloaded installer file and check if it helps. If the name of the downloaded installer files comprises multiple words, rename it to have only one word for e.g.
SoftwareNameInstaller.exe.

Step 2.

You can also try downloading the software installer file from another approved source and check if it helps.

Step 3.

I also suggest you to run virus scan (Microsoft Safety Scanner) and check if it helps to resolve the issue. If a computer is infected by a virus, lots of resources will be taken up to greatly slow down computer performance.

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

Hope this helps. Post us with the status we will be glad to help you.
