1>MSVCRTD.lib(ti_inst.obj) : fatal error LNK1112: module machine type ‘X86′ conflicts with target machine type ‘x64′

this meant “you properties -> VC++ Directories -> Library Directories” is pointing to a directory that has 32 bit libs built in it. Fix somehow!

In my case http://social.msdn.microsoft.com/Forums/ar/vcgeneral/thread/c747cd6f-32be-4159-b9d3-d2e33d2bab55

end-of-data detected scsi sense data

rogerdpack — Fri, 10 Feb 2012 21:33:59 +0000

this with an on drive verify “error” sense data response of

f0 00 08 00 00 00 01 12 00 00
00 00 00 05 00 00 00 00 32 05
10 01 00 00 00 00

(08 00 05) meant “when passing in the verify command, you have too many values in the length field, so it’s expecting more files than are on tape” and erring.

visual studio express how to bundle visual studio msvcrt redistributable

rogerdpack — Thu, 09 Feb 2012 16:29:27 +0000

looks like if it’s with inno setup, it’s either execute the msi file or “static link” against msvcrt10.dll (et al)

http://stackoverflow.com/questions/2461848/distributing-vc-redist-running-installer-when-already-installed-causes-prob

Apparently microsoft frowns on static linking dunno why.
