Visual Basic issues in Windows August 2019 Updates

Microsoft added a new known issue to all cumulative updates that it released for Windows client and server versions in August 2019.

The issue states that applications may stop responding if they use Visual Basic 6, Visual Basic for Applications, or Visual Basic Scripting Edition. Apps may throw the error "invalid procedure call error" in that case.

After installing this update, applications that were made using Visual Basic 6 (VB6), macros using Visual Basic for Applications (VBA), and scripts or apps using Visual Basic Scripting Edition (VBScript) may stop responding and you may receive an "invalid procedure call error."


...Organizations -- and the bug affects organizations for the most part -- who run apps or tools that require a Visual Basic flavor may want to block the August 2019 updates until the issue is resolved. Those who have installed the patches already can uninstall the Windows Updates to resolve it.
