Error installing Amyuni printer on x64 systems

[italital]

Hello,

I have a problem installing an Amyuni PDF Converter printer on some 64 bits based systems.
My licensed version is 2.51-b, and I try to install it (with the Install.exe /s command in a batch file) on a Windows Vista x64 and on a Windows Xp x64.
Well, I get the same error message "Error Code: 87 - The parameter is incorrect", and the installations fails. Here is the full log of Vista installation and of the Xp installation:

How can I resolve this problem? Is my version to old?

Thank you for your help!
Best regards
