Error while running SharePoint Configuration Wizard before upgrade

Question

I am trying to to run SharePoint Configuration Wizard before starting the new patch. Even though, I have not made any upgrades yet, I am facing the below error:

An exception of type System.IO.IOException was thrown. Additional exception information: Access to the path 'C:\ProgramData\Microsoft\SharePoint\Config\3ff6d5fa-1354-4794-b1ef-8b72096f83eb\' is denied.

Any suggestions?

Answer 1

For the following problem, I checked for the permissions the account has with which I am trying to run the configuration wizard. I also tried with the System Account/ Farm account but still the same error was displayed.

I came across two blogs which had the same steps as given here. In both of the blogs, it shows that the error is because of the config cache file. Instead of following those steps, I tried resetting the IIS and that didn't work. Then, I just restarted the servers, and the Configuration Wizard worked fine.
