Hi, I am new at GoblinXNA, and I just installed all the programs needed, but on Camera Calibration solution I got an error that ALVARWraper.dll file isn't in the unmanaged folder. So I tried ALVARWraper solution and I got to the conclusion that I needed ALVAR 1.1.0 so I installed it, and it worked, but I still get a crash:"Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang." Is ALVAR 1.1 problem or something else?

Try use the Goblin 3.6, he use an ALVAR 1.5, expiration date in 2012.

I am using 3.6, but cameracalibration in tools in goblin 3.6 is using ALVARWraper.dll, not ALVARWraper150.dll...

I guess that it has to do something with several threads in a single process, but I'm not very good in threading, so, I don't realy know how to fix it...
