Hi,
There is detailed steps listed over in this thread and you can follow the steps to resolve this Win32 error.
To unblock you, you can enable SSO manually through PowerShell. I've included the instructions below:
Location of SSO PowerShell scripts
a. Open PowerShell
b. Navigate to %programfiles%\ Microsoft Azure Active Directory Connect
c. Import AzureADSSO.psd1 by calling: Import-Module .\AzureADSSO.psd1
To enable SSO for a new forest:
a. Call New-AzureADSSOAuthenticationContext. This should give you a popup to enter the cloud admin credentials for the tenant
b. Call Enable-AzureADSSOForest for each forest you would like to enable SSO for. This should give you a popup to enter the domain admin credentials.
To enable SSO for your tenant (this is the last step):
a. Call New-AzureADSSOAuthenticationContext. This should give you a popup to enter your tenant creds
b. Call Enable-AzureADSSO and pass ‘true’ to enable SSO
Hope this helps.
