6Foot2 Posted January 8, 2007 Posted January 8, 2007 Hi all, I am logged on as administrator trying to download and install the latest Shockwave player and I get this error: 'Unable to authenticate installer' [Picture Attached] Anyone else seeing this/cured this? Help would be appreciated. OS: Windows XP Pro: SP2
6Foot2 Posted January 22, 2007 Author Posted January 22, 2007 OK now I can install/update Shockwave, but I am now getting the 'Unable to authenticate installer' message from the Flash Player installer. Anyone else getting this?
Geoff Posted January 22, 2007 Posted January 22, 2007 The certificate used to sign the installer is invalid or has been revoked.
