Hello,
On your IIS server or PC, in the Start menu, right click on "Dynamics NAV 2017 Administration Shell" and choose Run as Administrator.
E.g.:
New-NAVWebServerInstance -WebServerInstance <<name>> -Server localhost -ServerInstance <<serverinstance>> -ClientServicesCredentialType Windows `
>> -ClientServicesPort <<clientservicesport>> -ManagementServicesPort <<managementservicesport>> -Force
A sample of possible values:
New-NAVWebServerInstance -WebServerInstance DynamicsNAV100 -Server localhost -ServerInstance DynamicsNAV100-ClientServicesCredentialType Windows -ClientServicesPort 7046 -ManagementServicesPort 7045 -Force
You need to replace the possible values with your own that does apply to your situation. Alternatively, raise a support ticket to Microsoft support via your CSP and we will assist you to get up and running. It must be frustrating when the application fails with errors. We are here to assist.
Thanks.

I've tried with all parameters and I got this error

Then I removed a few ones and I got those two.
My C:\Program Files\Microsoft Dynamics NAV\100\Web Client folder is empty, is that a problem?
