Failed to Activate 'VB.UserControl'. This control may be incompatible with your Application.

This error message comes up when launching Velocity and HirschGrid.ocx and Hirschgrid2.ocx are not registered. These files not being registered usually happen when KB updates are applied and the account logged in does not have sufficient permission to register files.

To fix this issue, follow the steps below:

  • User will need to register both HirschGrid.ocx and HirschGrid2.ocx files. There are two ways to resolve this:

    • Register files in Velocity Directory

      • Navigate to the Velocity Directory (C:\Program Files (x86)\Hirsch Electronics\Velocity), locate the HirschGrid.ocx and HirschGrid2.ocx files, drag and drop each into the REGSVR32.EXE, which is located in the same Velocity Directory. OR

      • Use Command Prompt - Start>All Programs>Accessories>Command Prompt. Once open, type the below commands:

        • regsvr32 /s "C:\Program Files (x86)\Hirsch Electronics\Velocity\HirschGrid.ocx"

        • regsvr32 /s "C:\Program Files (x86)\Hirsch Electronics\Velocity\HirschGrid2.ocx"
