7.x: Unable to install EurekaLog on Windows 2000 and Windows XP
Posted by Aleksandr Alekseev on 16 January 2019 12:23

Problem:

I get "Installer's executable is not signed" / "Installer's executable has not been signed" message when installing EurekaLog on Windows 2000 or Windows XP without SP3 installed.

Reason:

Windows 2000 does not support SHA-2 (SHA-256/SHA-512). The support for SHA-2 is available since Windows XP SP3. Missing SHA-2 is the reason for failed signature check on installer, because certificates for HTTPS and digital signature use SHA-2. 

Solution:

Please, contact our support, we will help you to install EurekaLog manually.

 

Additional notes:

  • Please note that EurekaLog's code itself still works on Windows 2000 and Windows XP systems. For example, you can develop your application on Windows 7 and deploy it on Windows 2000 - it will work just fine. Only installation of EurekaLog is not supported for Windows 2000.
  • We used double-signing earlier (e.g. sign with both SHA-1 and SHA-2 at the same time). Unfortunately, our old SHA-1 certificate has expired a long time ago, and all new certificates are available in SHA-2 only. Sadly, we can no longer support installation on Windows 2000 - simply because we can not get SHA-1 certificate anymore.
