!()notation, or you can file an issue either at https://github.com/microsoft/iqsharp/ for IQ# issues or https://github.com/microsoft/QuantumKatas/ for kata issues with more detail about the context in which you're encountering these errors. That in turn could help us solve the problem better. That said, in the meantime, installing IQ# as an administrator isn't generally necessary unless your Jupyter installation is locked to Administrator only; in that case, you can always opt for a user-local installation by using
dotnet iqsharp install --userinstead.
