Changing Excel Settings Using VBA - Creating Customized Userform

I'm using the following code to create a customized userform, and it works perfectly on my computer, as I've enabled all macro settings.

Code:
Function GetOption(OpArray, Default, Title)
Dim TempForm 'As VBComponent
Dim NewCheckBox As MSForms.CheckBox
Dim NewLabel As MSForms.Label
Dim NewCommandButton1 As MSForms.CommandButton

[Code] .......

However when my coworkers need to use the code it creates an error, as the VBA project is unsafe.

Now my question is, can you write some code that enables all macro settings temporarily, in such a way that my coworkers can use this code?
