It is not possible to collect Comodo free (or other) Email Security Certificates on computer running Windows Vista.

Here it is: On Computer running Windows XP or other, but no Vista: Note: Do not use the web page addressees, use this procedure. 1. Turn off you Windows Vista machine. 2.

This can work for You solution but Vista does support cert in e-mail, you vendor has a work around, other with nativily with vista

Hi JAYTF, Please can you explain: "other with nativily with vista". The issue is to be able to collect the certificate. One's collected on XP machine and imported (the certificate via floppy) I can use it to signed and or encrypt my email - that works. But to collect the certificate I hat to use Windows XP machine. IE7 is on bough machines. Andrejmart
