I received a "Can't Create Control:..." message when opening all Sage Setup Option forms in Sage 300 2017 running Windows 10 with MS-SQL 2012 (standalone). Increasing screen resolution did not help.
The error is displayed in the following circumstances: Setup Options for all modules; G/L Reports - G/L Source Journal, Accounts; G/L Accounts - Accounts form; Bank Services: Setup|G/L Integration. Banks; Bank Transactions - Reconcile Statements
A/R Setup: Salespersons, Items, G/L Integration
A/P Setup: G/L Integration, Payment Selection. Vendor form and Vendor Activity; Recurring Payables
A/P Transactions: Invoice Entry, Create Payment Batch, Control Payment, Adjustment Entry
Changing the screen resolution did not help
