P6 R8 up. Import Export of WBS, OBS, and Activity Codes Dictionaries

Sorry to bother on the same old stuff but yet I won't find ANY definitive and clear answer, so here it comes the question once again: is there any chance, no matter what, for any of the  version R8.2 to R15.2, and working with a SQLServer 2008_R2 to import and export the dictionaries? Someone tells me to install SDK to use the excel tools available: well I have installed it but it turns out that SDK, on my R.8.2 doesn't fit 64bits requirements; so I go ask someone.else (here on Oracle Support) and I am told that rev.15.2 fix the problem of SDK working with 64bits, then I come here and acknowledge that excel tools that are supposed to do the import/export, were not upgraded to work with 15.2.
