Silent installation

[bendrouet]

Hi,


I have to test the presence or not of a file during my installation and if it is present I have to switch to silent installation.

The problem is that when I use the SILENT predefined variable set to TRUE or FALSE I hva some strange behaviours from my program.

When I run it step by step with the debug mode, all works correctly, when I run it one shot, it crashes saying me that some variables are not defined.

So I decided to avoid the use of the SILENT variable because I could not found why it worked in one case and not in another.

I use now the condition variable present in the DISPLAY DIALOG function.
So my variable is called NODISPLAY and I initialize it at FALSE

When I found the file its value is set to TRUE

So in my DISPLAY DIALOG function, I set the variable NODISPLAY with the condition FALSE

SO all is perfect, the silent installation works good but when I want to uninstall the program via the uninstall shortcut or via the control panel, add/remove programs, I have an error message saying me that the NODISPLAY variable is not defined !!

I can not appearly set a silent installation without a lot of problems

Can someone help me ?

The operating system is WinXP

thank you

It seems that the variable NODISPLAY should be initialized in the Define Setup Globals Region

The program runs now correctly.
