Installation

I have been using this program for a few years now but my hard drive died so I replaced it and upgraded to win 8 and got a new security program (eset smart security) and now LibreOffice will not install on my PC. I get this message saying “Windows can not access the specific path or file. You may not have the appropriate permission to access the item” . Any suggestions on how I can get it to install? Thank you in advance for your help.
Blessings,
Mary
