Cryptographic Services Service, otherwise known as CryptSvc, is the thing that causes a pop up to display that the program or update about to be installed does not have a valid certification. If there are errors coming up with the Cryptographic Service then it should be fixed right away as this will often be the final reminder that is provided before an unknown publisher file is downloaded onto the system and potentially hurt or infect your system. The Cryptographic Service error message is not a good one to see and below are some ways to resolve the error.
The possibility of leaving your system open to infection is not a good thing which is why there are a couple of things that can be done to try fix the problem. The first thing to try doing is to ensure that the Cryptographic Service is actually running on the computer. The error code might be displayed if the system is trying to locate the Cryptographic Service and it is not present. The way to do this is to go into the Control Panel of your system, select Administrative Tools, then click on services. Once Services is open select Cryptographic Service from the list of the names that are provided. If the service is not started highlight Cryptographic Service and select Start. This will start Cryptographic Services up and should resolve any of the issues encountered.
If Cryptographic Service is presently running then the best thing to do is to manually end that process. Once the process has stopped working you can select Cryptographic Service and start it again from the beginning. Sometimes the service just needs to be restarted to resolve the error that is being displayed.
Another cause of the Cryptographic Service error code for being displayed is if there is some level of corruption with the file itself. If this is the case the best thing to do is to check to see if there are any updates available from Windows and Microsoft. In some instances updating the current service pack can resolve the errors that are being encountered as there are fixes in the patch files.
Once the Cryptographic Services Service is working again the next thing to do is to run a full registry scan to ensure that the out of date service, or remnants of it, are no longer around. By scanning the registry it is possible to identify issues and errors that could cause more Cryptographic Service error codes to be displayed at a later time.
