proposed solution

Actually, fread is not to blame. Thinstall hooks its own procedure to lots of
kernel32 entries (I assume in order not to pollute the disk with lots of
temporary files, but rather look at them in a compressed way from the
executable itself).
And Thinsall did not hook into SetFilePointerEx but only SetFilePointer.
So changing our msvcrt to use only the former (and no longer the later) seems
to satisfy the installer.
