Pre Necessary System:	PVAcoustics Software
	PVAcoustics is currently available only on Windows platform. A Linux version is being studied. Framework must be installed so that PVAcoustics functions. It is installed in theory on the machines assembled with Windows Xp or Windows Vista. But if you miss it you can download it on the site of Microsoft. It is about the version redistribuable, that is to say version 1.1 or version 2.0. The downloadable file names DotNetFx.exe. PVAcoustics could be installed before Framework but will not function as much as this one will be missing.
Remote loading of PVAcoustics:
	You can download the last version of PVAcoustics while clicking on the bond  PVAcoustics.ZIP It is about a compressed file of the program that it will be necessary for you to extract then to install.
Suppression of PVAcoustics:
	You can uninstall PVAcoustics.exe via the control panel since the menu on Windows or by clicking on the icon of desinstallation of the program in the menu of Windows in the PVAcoustics repertory.
Three operating conditions:
	The Mode “Demonstration Attached” has five tests which make it possible to take in hand the software and to sail in its great functions, free. Mode “Demonstration Recorded”, free which raises the bloquage to five tests and authorizes certain functions but with the constraint of having to connect itself on Internet and to inform that you use PVAcoustics. The “unslung” Mode which is paying and releases the entirety of the functions of the software.
	What allows the free recording? - allows to be held with the current of the updates - the limit of the five tests withdraws - the blocking of screen printing releases - the blocking of the impression of screen releases - allows to add its clean loudspeaker to the data base - allows to print the data base - allows to reach the first page of calculations of the filters - allows to post the alternatives n°2 plans of the enclosures Bass reflex camera and Closes What allows the purchase of a licence? - a complete débridage of all the functions of PVAcoustics allows. - the licence is valid without time limit for a person and a machine. - This one is worth 65,00€ for a machine and an additional person then 10,00€ by machine. - the updates are free. A licence can be obtained only after installation of the software on your machine and recording while following the procedure of the form of recording by validating each stage required by this one. You will receive by return of email your number of licence to be filled by simple copying/sticking in the box of the form envisaged for this purpose. The purchase and the payment can be done only via PayPal which makes safe all your transactions; it is enough to click on the button of PayPal and to follow the instructions. In all the cases PVAcoustics can evolve thanks to you.
