A Windows Smartscreen error is displayed when installing PVsyst on Windows 8

Recommended Posts

When trying to install PVsyst 6.x on Windows 8, an error message from the SmartScreen service could be displayed:

"Windows Smartscreen prevented an unrecognized app from starting. Running this app might put your PC at risk."

Do not panic, if you downloaded PVsyst from http://www.pvsyst.com, PVsyst installer does not contain any viruses or malwares.

PVsyst is a regular application, it beneficiates of an official "signature" delivered by an independent organism.




To get rid of this message you have to turn off the Windows Smartscreen service:

  • * Open up the classic Control panel >> System and Security link >> Action Center.

    * Expand the security list and look for the Windows SmartScreen >> Change settings.

    * Turn off the Windows SmartScreen Filter and validate.


Then you can start again installing PVsyst.
