Build 2 is a maintenance release. Lumion 64 bit version could not start on some Windows installations because of errors in the build configuration.

Fixed:
- MSVCRT runtime dependency errors
- DirectX dependency errors

Hello. I am very interested in buying the lumion, so download the trial, to know it, but gave me problems, I got blue screen, and I closed the windows, which surprises me because my computer has never had any problems in any other program . my computer has an Nvidia GeForce 525M GT graphics card  of 1Gb, has a 4Gb ram,a processor Core i5 2410M, 64bit. I need to know the problem to determine whether or not to purchase lumion.
thanks

We'll have a demo soon of the new version with some extra efforts to increase stability. Most of the crashes are caused by either hardware failure (low power, GPU too hot) or driver errors.

Lumion is one of the most demanding applications there is for your GPU so a small error in the driver can make it crash. One fault we found was for example when we do gamma correction on a black color we do the formula pow(color,2.2) in a shader which should of course be no problem because it's a perfectly valid statement. However, it resulted in instability and strange gfx errors on some NVIDIA cards. As it turns out the pow function is compiled in a way so it resolves in a division by zero which has the possibility to crash the 3D card. We are now deliberately installing unstable 3D cards here now in the office to track down problems like this and find a solution.

I also noticed some laptops have Optimus and they crash, blue screen etc.. probably because of the way it switches between GPUs. In this case you can disable Optimus and prevent any problems like this.

A blue screen essentially means the driver crashes. In most cases the OS can pick this up and reinitialize the driver but in some cases the driver pulls down the entire OS. Ofcourse a driver should never crash but there are bugs here and there as the one described above we are trying to find errors like this and work around them. These errors are very specific for certain 3D cards or drivers so they are quite hard to find.
