I'd like to add another possible cause of this error: when I built by MSI for application I added the CRT merge module, but forgot to add the police merge file for it.

After way too much time spent looking for a reason for why Windows couldn't find the CRT DLL I rebuilt the MSI with the policy merge added and my blood pressure could return to normal. Phew.

Not sure if VS adds the policy file by default, but the MSI builder I use sure didn't.
