[mlottner]

@kartheekakkur Thanks for providing your results. The product engineers are now trying to understand the issue and we will revert back as quickly as possible.

[mlottner]

@kartheekakkur It’s seems to be either a permissions issue or the config file is corrupted.
Can you confirm you are running the script as Administrator, and that you have permissions to the directory the files are located in?

[kartheekakkur]

@mlottner Yes I ran the poweshell with admin permissions and I manually pasted the values in the config file it was referring to as well, its I had the issues.

Method invocation failed because [System.Xml.XPath.XPathEvaluator+d__1`1[[System.Object, mscorlib,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]] does not contain a method named 'SetValue'.

[kfbehar]

@kartheekakkur, it seems that you care trying to run the scripts from their location in the repository, while they are intended to run after you build the solution.

1. Navigate to srcModulesSecurity
2. Run dotnet publish –c -r
3. Go to the install directory that is under the output folder here: srcModulesSecuritybinnetcoreapp2.0publishInstall
4. Run the install scripts from there according to the docs

[mlottner]

@kartheekakkur Please let us know if the latest instructions from @kfbehar helped and you have now succeeded, or if you still need assistance.
