Installation went well but starting PVsyst fails, what happened ?

When PVsyst is starting, Windows checks if it is coming from PVsyst SA to ensure this is an authentic version. It guarantees you that PVsyst is virus and malware free.

If this check is failing, a pop up will display: "The application can not start because it is not signed by PVsyst SA."

 

If you downloaded PVsyst from https://www.pvsyst.com, the problem must come from the fact that Windows does not contain our security partner's certificate.

 

Please follow this procedure to update the Windows certificate list:

oStart menu >> Control panel >> Add or remove program >> Add/Remove Windows component.

oCheck "Update Root certificates".

oClick OK.

oRestart the computer.
