Technical aspects > Install and uninstall PVsyst

Install

PVsyst installation file is available at https://www.pvsyst.com in the Download section.

•Download PVsyst-7.x.x-setup.exe

•Double click on it, it could show a security warning: the editor must be PVsyst SA (otherwise contact us). Accept it.

•If the computer already host a PVsyst 7 version, a dialog asking to upgrade or do a parallel install is displayed:

•Upgrade (recommended): the old version of PVsyst 7 will be removed (user data are kept safe) and the new one will be installed.

•Parallel install (for advanced user): the old version of PVsyst 7 is not removed and the new one is installed in a separate folder. The new one will use another user workspace: if you still want to use the same workspace keep in mind that backward user data compatibility is not guaranteed. Anyway, this solution is useful if you need to deal with old PVsyst versions.
Warning: it is not possible to install multiple patches of the same minor version in parallel, even though the installer gives the choice

•Accept the license agreement.

•Select a folder to install, basically the default one in Program Files is a good choice.

•Accept or decline the collection of anonymous data.

•When you are ready, click on Install and accept to elevate your privileges to Administrator when asked.

•When installation is done, start PVsyst with the desktop icon or from Start menu (PVsyst 7.x.x).
