How check if add ins run?

[20rin]

Hi,

I use Excel 2010 and I have installed Vision Excel.
When I log off from vision, calculation mode is "manual". How I can set "automatic" using VBA?

I thought something like:
If "vision is activate" = true
then
Application.Calculation = xlAutomatic
....
:help

How do you log-off from Vision?

Add ins > Vision > Log off
