My acrobat doc pdf browser plugin in missing

Sorry I am new to this.  I have Windows 7 and updated to the new Window 10.  Windows 10 was slowing me down and my internet.  I went back to Windows 7 and when I went back to Windows 7 then it removed parts of my acrobat reader and I could no longer view my PDF documents.  It told me to reinstall acrobat reader DC.  So I tried that and I am even having problems accessing the adobe website as it is saying my acrobat DC PDF browser plug-in in missing.  So it get to 90% full of downloading than it says that the feature I am trying to use is on a network resource that is unavailable.  Click OK to try again or enter an alternate path to a folder containing the installation package AcroRead.msi in the box below.  I am using Internet Explorer and doing the same thing on Goggle browser.
