Internet Explorer blocks download with signature or certificate notification

Problem

When I try to download think-cell with Internet Explorer, I get a message like:

signature invalid error message signature invalid error message

Explanation

The cause is most likely in some local configuration with regard to which digital certificates your machine trusts. To the best of our knowledge, our installers are correctly signed and also comply to the changes Microsoft made.

Solution

Please review (or have your IT review) the certificate settings on the machine. If your IT believes everything is in order, please do not hesitate to contact our support team and include details about the error. (Follow the instructions in the error message to see the details, e.g., click the Learn more button).

Alternatively, you may try another browser such as Firefox or Chrome to download think-cell.
