Hey guys, Since I get a lot of my development help from the internet and any further questions from helpful forums such as this one, I haven't noticed this earlier, but I am missing all of the help (html) documents from my SDK folders. I install the SDK from my original FSX disk 1 and everything is there in the SDK, then SP1a and check again and all of the tools and documentation are there, but then after installing the Acceleration SDK there are no documents. All I am left with is the various tools, compilers and example files but the help documents are all gone. I thought it may be a problem with my Acceleration installer so tried reinstalling using the SP2 version of the SDK from Microsofts website but the same thing occurs. Is this normal? for the time being I have just backed up a copy of all the help docs in a separate folder for reference. Any advice would be appreciated.
