Developper account setting up issues

Error 40005 BDK_E_REQUIRED_FIELD_MISSING indicates a problem with the enrollment flow, but the core blocker in this scenario is that the account was originally created as an Individual developer account and now needs to be a Company account.

Partner Center does not support converting an existing Individual developer account into a Company developer account. To enroll as a company, a separate Company developer account must be created and used going forward.

Actionable steps:

1. Keep the existing Individual account as-is (it cannot be changed to Company).
2. Create a new Company developer account using a Microsoft account that will represent the organization:
   • Go to the registration entry point for Store/Partner Center signup (for company accounts, follow the company flow described under “Open company developer account”).
   • During signup, select Company as the account type. Note that account type selection may be limited or pre-determined based on the Microsoft account and region; if Company is unavailable or greyed out, follow the guidance under Account type availability in the documentation.
3. Complete all required company details and verification:
   • Provide business information and, if available, a DUNS number or upload official business documents.
   • Provide company contact info and a publisher display name that the company has rights to use.
   • Pay the one-time Company registration fee (approximately $99 USD, varying by country/region), unless using a new zero-fee company flow where applicable.
4. Wait for company account verification to complete. Company verification can take from a few days to a couple of weeks.
5. Once verified, use the new Company developer account for all company app submissions.
6. If the 40005 error persists when attempting to start a fresh company enrollment, or if the system continues to force the Individual flow, raise a support ticket so support can review the specific GUID and enrollment state:
   • Use the Windows developer support channel referenced in the documentation to open a ticket for account creation/onboarding issues.

Because the platform does not allow changing account type, resolving this scenario requires onboarding a new Company developer account rather than retrying enrollment on the existing Individual account.
