This is once again a regression since 1.5.0p17 and Werk #7167 and addresses two issues:
By invoking cmk-update-agent.exe with --reinstall or --force flag, the reinstallation will almost certainly get invalidated with "MSI Installation failed", because the agent hash would not change. This is now mitigated by tolerating an unchanged hash in that situation.
After an installation gets invalidated with "MSI Installation failed", there is a chance that a still working agent installation gets broken, because some important consistency checks do get canceled by this invalidation. This is now mitigated by changing the order of post-agent-update-checks on windows.
