This error occurs only on Windows Server 2008 R2, same error in two different servers.
Windows 7, Windows 10, Windows Server 2012 are ok.
What could cause this error ?
Any help would be greatly appreciated.
I´m using Xailer 5.1.2.
Could anyone test with Xailer 6.2 or send me the executable in this version ?
I've attached the project that generates the error.
