A Certificate Chain Could Not Be Built To A Trusted Root Authority


Answer :

I also met the same issue in Win 7 sp1.

The solution is below:

  1. Download the certificate file from Microsoft: MicrosoftRootCertificateAuthority2011.cer

If the link invalid someday, you can download from MicrosoftRootCertificateAuthority2011.cer - github.

  1. Double click the .cer file downloaded just now, then install the certificate following below captures:

Step1


Step2


Step3


Step4

  1. Re-install your .NET Framework 4.6.2 installation package.

Then the problem will be resolved. May it be helpful for you.


I recently ran into this issue with systems behind a firewall that didn't have internet access. I ran /extract on the .NET Framework 4.6.2 MSI and was able to run the x64 installer directly without the certificate check. Maybe not the "right" way to go, but it worked.


could it create problem to install the same certificate on several systems?

No, it will not be a problem even if the systems would be connected to the internet in the future.

When you connect the system to the internet and do the update it could download a pack of trusted certificates. These certificates will be added to the trusted root store. Existing ones will simply be IMO simply replaced.

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz

Can Feynman Diagrams Be Used To Represent Any Perturbation Theory?

Answer : Diagram machinery works also for perturbation theory in classical statistical mechanics and classical field theories. Generally, various kinds of diagrams constitute a pictorial way of talking about tensor products and their contractions while hiding the multi-linear algebra from the layman. In the simplest case, vertices (or blobs) represent vectors, matrices, tensors; vertices have ingoing and/or outgoing ports; ingoing ports denote (contravariant) ro indices; outgoing ports denote (covariant) co indices; directed arcs between blobs give a pair of equal indices summed over; different base spaces ⇔ \Leftrightarrow ⇔ different arc types; symmetric tensors ⇔ \Leftrightarrow ⇔ undirected diagrams; no labels are needed for internal lines. In many cases, the directed arcs are decorated (as thin, thick, broken,wavy, curly lines), each decoration indicating the presence of a so-called propagator, a function of its label to use as a weight in the sum, which may beco
