Security Warning
Warning: The authenticity of this software can not be
verified, therefore this software cannot be trusted.
Problem/s listed below:
<description of problem>
Are you sure that you want to install and run <program>
distributed by <Publisher>?
Microsoft has increased Authenticode security in Internet Explorer to ensure that all digitally signed self-extracting executable files are fully protected. Many signed files created using older versions of third- party tools such as Package For The Web from InstallShield or WinZip Self Extractor from Nico Mak Computing are now treated as unsigned files. When the safety level for active content is set to High or Medium, the message is displayed when you attempt to download these files.
To work around this problem, contact the administrator of the Web site that contains the self-extracting executable file to report the problem. Digitally signed files created using the most recent version of a third- party tool should not cause the message to be displayed.
The third-party products discussed in this article are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
