2017 Premier will not complete installation on server

We have just installed Reckon Premier 2017 and are now experiencing the annual hosting error, but this year is different.  I am now unable to complete the installation of 2017 on our server, the reason given is that the installation has been disrupted.  It then ask that I install the previous years version, which I did, but it now will not complete the installation for 2016, giving the same reasons, that the installation has been disrupted.  Very frustrating.  Can anyone offer some assistance with this error?
