recently all links in new pdf-files open in the webbrowser instead of in adobe acrobat as it used to, how do I change this back?

Creating pdf-files, that include links, from Word or other programs via pdf-maker. When opening the pdf-file in Adobe Acrobat and clicking the links, the new file (which is a different pdf-file on the computer), opens in Internet Explorer. This started in the last weeks. Normally the links have opened in Adobe Acrobat or in Acrobat Reader. I prefer to open them in Adobe Acrobat/Acrobat Reader, how do I change this back?

I know I can change setting in Internet Explorer so it does not open there, still I´m not content with this as I have to change every computer and the links still try to open in the browser. What has changed?

Best Regards
