I installed SPS12 and when I access webide and try to build database module, I get the same error as you mentioned above
Build of nareshtest failed. Builder 'mtabuilder' is not available for workspace workspace546nnbvigd48f0gk.
I see that you resolved this by reinstalling 1.0.17 but SPS12 comes with v1.0.24. So i dont think version is problem in my case?
Any ideas?
