Fix Requested Type Library or Wizard Is Not a VBA Project Error in Access
Question details
Users encounter an On Open error stating that the requested type library or wizard is not a VBA project when trying to run compiled applications.
- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Opening a compiled Microsoft Access database or a form containing VBA code after installing a new Office build update.
- Observed behavior
- An error message appears stating the requested type library or wizard is not a VBA project, which breaks Microsoft Access runtime applications even when VBA references are perfectly intact.
Check your current Microsoft Office build number by going to File > Account in any Office application, and confirm if KB5002121 or a recent patch was installed.
Roll Back Office to a Previous Stable Build
Reverting your Microsoft Office installation to a previous version bypasses the problematic update (like KB5002121) that breaks Access runtime.
Since this error is a known issue caused by specific Microsoft Office build updates, rolling back to the version immediately preceding the update is the most reliable workaround until Microsoft releases a permanent fix.
Click the Start menu, type 'cmd', right-click on 'Command Prompt', and select 'Run as administrator'.
Type 'cd %programfiles%\Common Files\Microsoft Shared\ClickToRun' and press Enter.
Type 'officec2rclient.exe /update user updatetoversion=16.0.xxxxx.yyyyy' (replace with your target stable build number) and press Enter. Follow the prompts to revert.
Open Access, go to File > Account > Update Options, and click 'Disable Updates' to prevent the buggy version from reinstalling.
Update to the Latest Patched Version
Install the latest Office updates in case Microsoft has already released a patch for the runtime issue.
Decompile and Recompile the Database
Clearing the compiled VBA code can sometimes resolve corrupted references triggered by a version mismatch.

Frequently Asked Questions
What causes the 'Requested Type Library or Wizard is Not a VBA Project' error in Access?
This error is typically caused by a botched Microsoft Office build update (such as KB5002121) that disrupts how Microsoft Access runtime applications process compiled VBA code, even if your VBA references are correct.
Does this Access VBA error affect all databases?
No, it primarily affects compiled runtime applications (.accde) and databases that automatically open forms containing specific VBA code 'On Open'. Standard tables and queries are usually unaffected.
Will repairing Microsoft Office fix this Access VBA error?
An online repair usually will not fix this specific issue if the bug is inherently present in the latest downloaded build. You must either roll back to an earlier, stable version of Office or wait for Microsoft to release a patched update.
