You need to set the burn variable MyBurnVariable1 to the value of your
ViewModel's InstallPath property before OnApply() is called. How you do that
depends on how your BA is structured.
One option would be to set that property in InstallExecute. Another would be to
have your ViewModel "bind" the two properties together.

> Hi,
> I am trying to install MSI from Bootstrapper. Install location for that msi
> should be specified from the text box in Bootstrapper UI. I followed this
> below example. in this example I added a text box for getting install
> location and I added below code pieces,and MyBurnVariable1 gets the value

> method, After the bootstrapper is loaded if I change text box value then
> start to run the msi MyBurnVariable1 is not assigned with text box value
> because Run method is not executed now, what should I do to resolve this?
> I am following the below example.
