Yoshimi Iida's patch on the msiExecStrCondQueryWithOptions
microservice. This patch makes the microservice return an empty result set instead of the string "emptySet" when "zeroOK" is set. To ensure backward compatibility, the old microservice is left unchanged and the patched one is named "msiExecStrCondQueryWithOptionsNew."
