I don't have access to a windows machine with administrator.
Are you trolling?
No, all of my computers are running OS X or Linux.
At work there is one Windows machine but I do not have admin rights to install Qt and MinGW.
i got acces to a win machine with admin rights at work, how hard is it to compile wallet? something that can be done without spending weeks on a learning curve? If so i got some free time at work both this and next week to look into it (what else should i do on my paid worj time)

if its not sorted by then, and its straightforward something you can read yourself upon doing, have never done it before.
