Report without body error

I’ve got an issue using a Xojo desktop app for reporting. My app works fine on my develope win10, but when I use it on my customer’s server, the report is without body.
Trying to understand and test, I’ve used “List Of Products Preview.xojo_binary_project” sample project and I build it as Win64bit with Xojo3.1, the app works fine on my win10 but running it on my customer’s server, the report is without body. It seems that something Xojo needs to generate the report is missing on my customer’s server.
My customer’s server is WinServer 2012 R2.

Any idea about what I check?

have you try generated the application as win32bit??
i think this version of the server is equivalent to window 8

Yes, 32 & 64 with Xojo3.1 & Xojo1.1; always the same result.
