DLL Missing

The problem is, that the required DLL is not actually even listed there.
There are just dozens of download adware links from the top to the bottom.

 

dll's work once then not

Hello,

System file corruption can cause issues with .dll files on your computer. To troubleshoot the issue, we suggest
creating a new user account on your PC and see if the same issues will occur on a new user profile. To do this, simply follow the steps below:

• 
  Select the Start button, then select Settings > Accounts > Family
  & other people > Add someone else to this PC.
  
• 
  Type a user name, password, password hint, and then select Next.
  

Once done with the steps, please get back to us with the results.

 

DLL Missing

I actually posted the link for the "list of troubleshooting steps to resolve your boost_threads.dll problems" which is located half way down the page. I did not mean to promote any downloads.

Why don't I just go back and indicate that on my original post? That way there's access to the 'step-by-step' instructions, which are accessed via those green 'plus' signs next to the topics.

If the link still needs to be removed, then let me know
