Summary: You may have noticed an error message that is displayed when downloading Tableau products using Microsoft's Internet Explorer indicating that there is a "corrupt or invalid signature". This is due to a change that Microsoft made on January 1st of this year to no longer accept software signed by certificates using the SHA-1 signing algorithm.

 

We've since obtained a new code signing certificate that does not cause this error message because it uses the stronger SHA-2 signing algorithm. We are quickly working to re-sign our software using the new certificate, so you will see this error less and less as we update our signatures.

 

Resolution: The following versions of Tableau Products are fixed:

Tableau Desktop, Server, Public 8.1.25

Tableau Desktop, Server, Public 8.2.18

Tableau Desktop, Server, Public 8.3.13

Tableau Desktop, Server, Public 9.0.14

Tableau Desktop, Server, Public 9.1.8

Tableau Desktop, Server, Public 9.2.6
