You can download the Android SDK Tools here:
A pre-requisite, if you do not already have it installed in to be running the Java Developer Kit, available here: http://www.oracle.com/technetwork/java/javase/downloads/index.html
You will need to ensure that suitable drivers are installed (if not already) on your device when connecting it to your computer via USB. I would recommend post installation of the 'SDK Manager' (in Administrator mode) and update the 'Google USB driver' if not already up to date. NOTE: You only need the "Android SDK Tool" package when checking for updates, you can deselect packages that the SDK thinks you may want.
I would recommend adding to the PATH variable in your Systems 'Environment Variables' (Windows > System Properties > Advanced) the following: ";C:\Program Files (x86)\Android\android-sdk\platform-tools;C:\Program Files (x86)\Android\android-sdk\tools;" (assuming that is where the SDK is installed to).
Then, run from command prompt "ddms.bat" which should spawn the 'Dalvik Debug Monitor' and if your devices drivers are installed, an instance will appear under the 'Name'. Select it, and you will see various log entries being recorded.
So, step through the process to cause the crash on your device, then in the DDM select a line item in the logging window and press CTRL+A (select-all), then press the SAVE (disk-icon).
