Windows 10: File association for installer file

I clicked on an installer file from Metastockfile extension .eik to install it. Apparently, since a Windows Update was waiting for install it instead brought up the pop-up for Open with... In that I accidentally clicked with the default "Always Open with this option clicked" and it selected Adobe Acrobat which was the first on the list. Now, I am unable to install that file. Whenever I double click it initiates Adobe Acrobat which obviously can't process that file. How do I remove this association and double-clicking on that .eik file initiates installation this was happening fine until yesterday.

*.dll files associated with other file in Windows7

Sounds strange, right?
Well the "picture" when in viewing a .dll file is incorrect, and I can compare it to the other accound on my system. I don't know if there is anything "wrong" with it, but lately some programs stopped working.

Can I somehoew, make them associated to correct "files"?

 

*.dll files associated with other file in Windows7

Are you talking about the icon for .dll files?

They are usually tied to a specific executable through the registry... have you been tweeking your system, or noticed any instability lately, pointing to memory or HDD data corruption?
