You have to install Qt first. You only need to install the run-time elements 
(ie. the DLLs) on the client's machine. Unless your application is licensed 
under the GPL (and you are using the GPL version of Qt and PyQt) then there 
are components of Qt that you must not install on the client's machine.

The only binary installer provided is for the GPL version of PyQt. Qt has 
separate installers. It's easy enough to use something like NSIS to create 
your own installer for your application that includes everything that it

In addition to your application you need to distribute the Qt DLLs (and 
plugins if you use them), the corresponding PyQt .pyd files and sip.pyd. If 
you are using the GPL version of Qt then you may also need to consider the 
MinGW DLLs. Finally you need to consider if you need to distribute Python 

You might like to look at tools like PyInstaller for creating single
