We ran into this issue when we migrated from Server 2003 to Server 2012, and New Atlanta Support told us the following:
BD.NET 7.1 will run on Windows Server 2012. The issues with using it are:
1. The cfdocument tag won’t work because the 3rd party library it uses, ABCPDF, only works with IE8 and earlier and IE8 won’t install on Windows Server 2012. We don’t have a contract with them to use their latest version. We’ve switched to a different product with BD.NET 9.
2. It uses Visual J# Version 2.0 Redistributable Package Second Edition which has a Mainstream Support End Date of 10/9/2012 and an Extended Support End Date of 10/10/2017.
So, in short is is because Server 2008 probably doesn't have IE 8 anymore, which is why the ABCPDF.dll is failing.
