An attempt was made to load a program with an incorrect format. File name: 'Leadtools.Kernel, Version=14.5.0.72, Culture=neutral, PublicKeyToken=9cf889f53ea9b907' --------------- The Leadtools.Kernal assembly is in the installation folder of the application so I would think it should be able to find it no problem.  Also, I did install the Microsoft Visual C++ 2005 Redistributable (in the past not installing this caused the same or similar errors), so I am thinking this is related to the server being 64 bit.  Using the same installer on other servers works great. Any suggestions?  I NEED to get this working very soon!    Report

This is because the libraries we use are really just wrappers around a lot of native unmanaged code, which needs to be built against a specific platform. If you need the 64 bit version of the binaries, download and compile your application in 64 bit mode using them. This however means you'll need to keep two versions of your application (one for 64 bit installs and one for 32 bit installs). If you've got a semi-sophisticated build system you should be able to keep the same source tree and do conditional compilation to achieve this cleanly. If you don't even want to think about the difference between 32 bit and 64 bit systems then just compile your app to target the 32 bit runtime (the x86 option) and use the 32 bit leadtools libraries. You'll loose the performance gains that a 64 bit system would otherwise afford you but shouldn't be any worse off than if the server was just a 32 bit server. Josh.    Report
