PDF Creator Display

I seem to have a problem with the pdf display once an file has been generated.

The file is placed on my DESKTOP but when I select the icon the file does not open with the latest ADOBE Reader.

I am not sure when this situation developed.

It seems to only recently happened after the installation of a utility, which has been removed.

Adobe Reader and PDF Creator both have been un-installed  the re-installed.

I do not believe I have altered any DEFAULT settings in either ADOBE or PDF Creator.

 I can copy it to storage device and connecting this to another PC, I can view the file.

So would anyone have any advice as to why I can not view the file.
