WINEPREFIX
By default Windows applications are installed in /home/user/.wine. If you want to install your application in a different directory then you must use the WINEPREFIX variable.
If you want your application to be installed in /home/user/appname you must first create the directory:
$ mkdir appname
Now type the following command:
$ WINEPREFIX="/home/user/appname" wineprefixcreate
This will create a directory called /home/frank/appname. In this directory you will find a fake Windows drive and the Wine configuration files system.reg and user.reg.
Now type $ WINEPREFIX="appname" wine setup.exe to install the application.
If your application is installed in /home/frank/appname/drive_c/Program Files/app/appname.exe ypu can run it by typing:
$ WINEPREFIX="/home/user/appname" wine ~/appname/drive_c/Program\ Files/app/appname.exe
