AqBanking - Adapt PATH Variable

[Daniel Gosselin]

Good afternoon,

I am running into trouble setting up aqBanking, I receive an error
that states: "If you have installed Qt already, you will have to adapt
the PATH variable of your system appropriately. Contact the GnuCash
developers if you need further assistance on how to install Qt
correctly."

I am using Windows Vista, I have installed Qt 4.5, but I cannot find
help anywhere on the internet to update the "PATH variable". Can you
help?

Thank you,

Dan
