24.0 compile doesn't genertae a manifest?

[DaveR]

Created a 64-bit Appsrc so I can screw around with 24.0 and 25 in 64 bit and not get in everyone else's way; but I do a mass compile of all sources and a lot of compiles fail with:

LINK ERROR: UNABLE TO OPEN FILE c:\devkfp\kirknet\Appsrc64\ITEMREQUESTH.exe.manifest
LINK ERROR: UNABLE TO CREATE EXECUTABLE

It's correct, the manifest isn't there, but the cfg file says it should be generated..

[Compiler]
Platform=x64
BeforeCompileProcessEnabled=0
AfterCompileProcessEnabled=0

[Application]

what am I missing?
edit: Should say it compiles in the Studio but my recollection is that the manifest got created by the compiler? (there's 580 src files about 60 of which did this so it isn't insurmountable - I just thought standalone compile generated a manifest in older versions)
