After you open up that link I sent you, scroll down the page till you get to the heading: Versions.
If you have SP1 installed in FSX, then click on the Download (192 mb).
If you have SP2 installed in FSX, then click on the Download (211 mb).
It appears that you need to download both SPs if your FSX has its SP2 installed.
Then the following extracted instructions need to be followed (if you have FSX SP2 installed):
FSX Deluxe SP2 users
For standalone SP2 users only !
(All Acceleration Pack users please see instructions below at FSX Acceleration Pack Users).
To install the SDK for FSX SP2:
- Download FSX SDK SP2
- Install the FSX Deluxe RTM SDK (see instructions above) - you won't need to do this as you already have the SDK.
- Install the FSX SDK SP1A (see instructions above)
- Install the FSX SDK SP2 that you downloaded
If you only have FSX SP1 installed then follow the instructions below:
FSX Deluxe SP1 users
To install the SDK for FSX SP1:
- Download FSX SDK SP1A
- Install the FSX Deluxe RTM SDK (see instructions above) - again you won't need to do this installation.
- Install the FSX SDK SP1A that you downloaded
However, the other instruction is:
Before applying any Service Packs,
you should copy the GMax installer folder to another location, (outwith SDK folder tree),
as applying the SP will delete the GMax installer folder.
I assume that the GMax folder must be part of the SDK service pack download. If this is the case, then you need to locate it and copy it to a location outside of the SDK (e.g. to Desktop).
These are big downloads and I hope they will prove useful in correcting your error. I've never had to use them, so am unsure whether your AH 2 problem will ultimately be solved with these downloads.
