Launch_story.exe is not working on PC!

Hi All, 

 

I have published my course to CD to make the learners able to run it offline. I am sure I have tried it and it was working. However, me and learners are now facing a problem running it. I think the PC prevent it as the extension is .exe. Any PC/Articulate setting to update so I have it work? 

 

I have attached shot of the window appear when I run the .exe file. 

 

Update: 

I have just published the same lesson to CD, and it worked! However, the old copy of it does not work! 

Now I cannot understand the reason why the older version does not work anymore .. I thought that a security reason blocks the .exe .. but it seems that this is not the case!!! 

Any advice please?
