# 2.4.5 vs 2.4.6 (VS Express C++ Desktop -- Win 7)

I've found a difference in 2.4.5 and 2.4.6 that has caused me to take pause. There's a problem in 2.4.6.

I installed 2.4.6 and have had lots of trouble installing and configuring it. It's was a lack of my understanding, newbie, on my part until I came across this, It's for 2.4.5,

They key to getting anywhere seems to be setting up environmental variables in the "System-> Advanced System Setting" (Control Panel). Those and some in the configuration. After the install, There are two values to set: TEMP and path. The first involves inserting OPENCV_DIR to the value, and the second inserting OPENCV_DIR value. The second requires setting the sys architecture, x86 or x64. That plus the compiler type, ..., vc9, vc10, ... Pretty simple.

For the configuration, one needs to change The Additional Include Directories, and the Additional lib Directories. $(OPENCV_DIR)\include and$(OPENCV_DIR)\x86\vc11\lib. Getting there requires one to work through a New Project, Solution Directory, to two Property Changes dialogs. These last two get the include and lib values above.

Here's my problem. The last values cannot be placed into the directories. How do I find the place to insert them in 2.4.6?
