Hi Sp0iLedBrAt, First, thank you for your posts (both #2 and the one I am replying to). I appreciate that the problem is that I don't fully understand all this, so I appreciate your trying to help me! I had a look at that page (again), but I'm just not sure what I need to do :-( Starting in the middle, from the 'Instructions', I have put my questions (Qn) inline - it is the packets issue that I am most confused about: I1) Download and extract to the work folder, the packet: 20100118_SNMsynth.zip (104.76K) Q1) What is the 'work folder'? This seems to imply that the file must be placed in a specific place rather than just to any folder I might choose, but it doesn't say where it needs to be? Therefore, I am working on the assumption it is just ambiguous language in the post, and they don't mean 'the work folder', they mean 'any folder'? Will this cause problems later? I2) Download 7-zip stand alone (if the link doesn't work retry until it works) and extract only the file 7za.exe to the work folder. I3) Download the packets you need to build your installer(s)/add-on(s), from supported file list above to the work folder. Q3) This is where I really get lost. How do I know which packets I need? I just want to get exactly what I would get if I ran all the DotNet updates from MS Update. The poster said I don't need all of them, but perhaps my best bet is to download all of them? If I do that, then run MS Update(after rebooting) will I then see no updates (for any DotNet stuff) in MS Update? If so, then that is what I want. On the other hand, is there some downside to using all of them? I4) Open _SNMsynth.ini and configure the building process to your liking, read the notes inside carefully. I5) Run _SNMsynth.cmd. If you are able to help with (Q1) and (Q3) then I would be most grateful. The biggest issue though is - nothing seems to happen! I do all of the above, run the cmd file, but nothing appears. I get an OUT1 folder, but it just contains a file called 'PROCESSDATA.TXT'. There is also an empty TMP folder. I am totally confused Thanks, Alan.
