Error message

You cannot specify "Purchased with product" value for "Registered" customer role

What it means

Thrown in the CustomerRole Edit action when the role's SystemName equals NopCustomerDefaults.RegisteredRoleName (the built-in 'Registered' role) and the model.PurchasedWithProductId is greater than zero. The Registered role is assigned automatically upon customer registration; binding it to a product purchase would conflict with that auto-assignment logic. NopException, caught and shown as an error notification.

Solutions

1. Create a dedicated non-system customer role (e.g. 'Premium Member') and set PurchasedWithProduct on that role instead.
2. Clear the PurchasedWithProductId field (set to 0/none) when editing the Registered role.
3. Audit any role-seeding scripts to only assign PurchasedWithProduct to non-Registered roles.

Example fix

// before — Registered role submitted with PurchasedWithProductId > 0 -> NopException

// after — assign the purchased-with-product linkage to a custom role
var premiumRole = await _customerService.GetCustomerRoleBySystemNameAsync("PremiumMember");
premiumRole.PurchasedWithProductId = productId;
await _customerService.UpdateCustomerRoleAsync(premiumRole);

// Before saving: the Registered role must not carry a purchased-with product
var role = await _customerService.GetCustomerRoleByIdAsync(model.Id);
if (NopCustomerDefaults.RegisteredRoleName.Equals(role?.SystemName, StringComparison.OrdinalIgnoreCase) && model.PurchasedWithProductId > 0)
{
    ModelState.AddModelError("PurchasedWithProductId", "Cannot set PurchasedWithProduct on the Registered role.");
    return View(model);
}

bool CanSetPurchasedWithProduct(CustomerRole role) => !NopCustomerDefaults.RegisteredRoleName.Equals(role?.SystemName, StringComparison.OrdinalIgnoreCase);

// The Edit action's try/catch shows the localized notification; use a custom non-system role instead.

When it happens

Trigger: POST to CustomerRole/Edit for the Registered system role with a PurchasedWithProductId > 0 (a product selected in the 'Purchased with product' picker).

Common situations: An admin tries to set up a 'buy X to become a member' flow and mistakenly targets the default Registered role instead of a custom role; a configuration tool applies purchased-with-product settings to all roles indiscriminately.
