🛑 Root Causes of the Error

  • The primary reason for this error is likely due to issues with the Windows Server 2008 R2 operating system. Specifically, the problem may be related to the way the server handles digital signatures or certificate validation. It's possible that the thawte code signing certificate is not being properly trusted by the server, causing the download to fail at 99%. Additionally, there could be issues with the server's configuration or settings that are preventing the download from completing successfully.
  • Another potential cause of this error could be related to the client-side configuration. Specifically, the issue may be due to outdated or incompatible browser versions (such as Internet Explorer 6.0.2900), which can prevent the download from completing correctly. Furthermore, the presence of antivirus software on the client PC may also be interfering with the download process.
