PMDG 737NG fs9.1 reinstall

[toothjockey 3]

Sorry guys,I know these questions have been asked before, but I did a search and couldn't find the answers. and lets face it, it's been several years now. :)I am doing a new install on a new computer. I have the 600/700 and also the 800/900.I found the original files that included the *.W02 files, but I also found a file "PMDG_737_THE_NEXT_GENERATION_V1-3.EXE".Can I use this v1-3 file instead of the original downloads? Or, do the originals need to be installed first and then v1-3?I also found the "Service Update Removal Tool", can anyone tell me what this is for?Hope someone will read this amid all the excitement of the MD11. :)Thanks,Don
