I have overcome the problem by downloading to my laptop, installing, then copying the complete program and installing onto my desktop.  Now works fine, in my opinion, not as good as Mendeley

I have tried to install Qiqqa several times, each time I receive error SP2 is reqd, this is already installed plus sp3.  I first wrote to qiqqa about a year ago, their answer we are aware of this problem and it is being addressed.  After reading the above I thought I would give it another try, same problem, it will not install.   
Any ideas how I may overcome this? 

Thank you for your reply.   I have contacted qiqqa and a no reply email has said that they are busy and will try to answer my question asap.
