Follow these steps to ensure the correct operation of your Optipe add-ins.

1. "Security Risk" Message (Macros Blocked)

If Windows blocks execution because the file source is not trusted:

  1. Close the installation file.
  2. In File Explorer, right-click the file and select Properties.
  3. On the "General" tab, check the "Unblock" box and click OK.

2. Did the add-in disappear? (Disabled Items)

If the Optipe tab no longer appears, Excel may have automatically disabled it after an unexpected closure:

  1. Go to File > Options > Add-ins.
  2. In the "Manage" dropdown menu, select Disabled Items and click Go...
  3. If the Optipe add-in appears, select it and click Enable.
Disabled Add-ins

3. Trust Center Settings

Adjust the security level to allow VBA projects to run:

  • Go to Options > Trust Center > Trust Center Settings... > Macro Settings:
  • Select "Enable all macros" (or notify).
  • Important: Check "Trust access to the VBA project object model".
Trust Center

4. Trusted Locations

To avoid recurring warning messages, add the folder as a safe site:

  1. In the Trust Center, select Trusted Locations.
  2. Click Add new location... and browse for the folder where you installed Optipe.

Did none of this work? Your Office installation might need a repair.
