Opening rptdocument created in iServer with free viewer

aburak

Hello,
is it possible to open rptdocument made with iServer by free viewer? I created a file with iServer 10, and when I try to open it with free viewer 2.3.1 it says: "The document file : E:Program Filesjakarta-tomcat-5.5.4webappsbirtCustomerDashboard.rptdocument does not exist or contains errors.", but that file does exist!

Can it be related to engine version difference (it it true that iServer 10 has 2.3.2 engine?)

Is this approach guaranteed to work on at least one combination of free/commercal versions?
