In case it helps...
I had a similar issue (same error) when I installed CodeWarrior 10.2 onto a Windows 7 x64 PC.
In your workspace directory, under .metadata there is a log file with no name (just called ".log")
In that file I had the following error reported:
java.lang.UnsatisfiedLinkError: C:\Freescale\CW MCU v10.2\eclipse\plugins\com.freescale.core.debugger.ddd_7.18.0.FSL_b10910\DebugDatabase.dll: The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail
Side-by-side loading usually means that it expected something else to have been installed that is relied on.
I had to install the "Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)" - NOTE its the 32bit package, which can be downloaded from Microsoft here:
Download Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) from Official Microsoft Downloa...
Once that was installed and I then restarted CodeWarrior the issue is no longer reported.
Hope it helps!
