(I do not have access to my lazarus installation at the moment, so I'm doing this from memory ...)
What is the path to your 0.9.29-xxxxx installation? Is it D:\Lazarus\...?
If not, I would find the path to gdb.exe within your 0.9.29 software and use the Lazarus configuration tool to point the debugger to the appropriate location.
Also, you can run both fpc and Lazarus from your CLI and review the error messages (if any). I could give you the command to run if I had access to my Lazarus notes. There are some hints in the Lazarus wiki on this topic, as I recall.
