I failed install SP14 runtime by ClickOnce.
Error message in log file is "CRRuntime_32bit_13_0.msi has changed since it was initially published".
I compared following A with B, and I confirmed that they were different.
A) PublicKey attribute in <PackageFile> element in product.xml
B) Public key of the .msi file's certificate signer. (by looking property dialog in explorer.exe)
Is wrong product.xml?
