I'm trying to install the Dropbox app on my computer, but it randomly stops.

My hard drive had to be replaced recently. I have attempted to download the desktop app in order to restore the dropbox files to my desktop where I typically work on them. The installation process begins then goes nowhere. I started to attempt this fix with the Geek Squad at Best Buy and he could not get it to work. I have attempted many, many times at home but still with no luck - including the off-line download (though I can't say I understand the distinction).

My files are clearly still in the cloud and appear to be working on two other devices (phone and IPad). These are the files that are most current for me so it is desperately important for me to get this to work. I even tried downloading a folder thinking I would have to store this work on my hard drive if I could not get the app to work - but each file is Read Only. 

Unfortunately I have a free account. It provides sufficient storage for the files I use in Dropbox. So I have no access to any support other than this forum. I would consider subscribing to a paid account if that would give me access to someone who could help. I have used Dropbox for years and have never encountered this or any other problem before. Please help if you can.
