I m using Installshield 11.5 Professional Edition. I have made a Basic MSI project.

What I want is when I try to install the application, when its already installed on the PC then it should not give me the maintenence mode i.e. Modify, Repair, Remove. It should do either one of the following:
1.) Pop a message that the <applicationname> is already installed & exit on clicking OK (or whatever button is there)

OR

2.) Give me only "Remove" option.

OR

3.) Reinstall the application without any messages.

I tried deleting the "MaintenenceType" dialog box and then try it but then it gave me error when I tried to reinstall saying some internal error "Dialog Missing".

I also tried deleting modify & repair radio boxes but then again it didn't work.

Any help will be appreciated. Kindly help .. this is urgent .

Open the Install UI sequence. There is an entry MaintenanceWelcome (with subdialogs MaintenanceType ...)

To prevent these dialogs to be displayed, edit the conditions of MaintenanceWelcom in the sequence.

default conditions should be:
Installed And Not RESUME And Not Preselected And Not PATCH

add a non defined property. Example:
THANKYOULAVOCAT And Installed And Not RESUME And Not Preselected And Not PATCH

So the maintenances dialogs will never appear while THANKYOULAVOCAT is not defined.


If you want the diplay your dialog which says the setup is already installed, just insert it above MaintenanceWelcome with the same conditions (except THANKYOULAVOCAT )
On this custom dialog you may add a button with the control event "EndDialog" + argument "Exit" (see the Dialog Behavior)

Thanks a lot for your reply. It really helped me.

But, there is a problem. I have created the dialog and added the button. Then under behavior I got PushButton1(Control Name) of Type PushButton. As you suggested I setted:
Event = EndDialog
Argument=Exit
for this pushbutton.

During reinstall, this dialog box appears perfectly but when I click the button the dialog box doesn't go away. I have also checked the sequence and this dialog box is placed exactly above "Maintenence Welcome".

Please suggest .

Thanks a lot again for your help.

Did you add a blank dialog or a "Wizard dialog"?

[technojewel]

I used blank dialog box.

Try to set 1 as Condition for this Event.

Sorry cudn;t reply earlier due to weekend.

Setting 1 as Condition solved my problem . Thanks a lot for your help.

More queries:
I want to check if the user has installed MediaPlayer9 or above on the system before starting installation. So, I think I need to put 'OR' between different conditions (to check media player 9 & 10, respectively). Or, I can check if the version of mediaplayer is greater than or equal to 9. I know how to search the registries for entries but the Property dialog that comes at the end is stranger to me (while making system search). I m using Installshield 11.5 Pro and making a basic MSI project

Please suggest me how to put these checks?

And thanks again for your valueable help without which my (already delayed) project wud have been delayed further. Thanks.

If you want the installer stop starting and display an error message ("Media player can't be found, ...") you must select "Store the value in property and use the property in an install condition". The other choice "Just store the value in the property" allow you to use the property where you want: in a component condition, in a feature condition, in a (Custom) Action condition like you did for the MaintenanceWelcome dialog.

Look at the UI sequence and you'll find AppSearch action which sets the property when searching the value. It is at the best place because it is before all actions so the property value will be available to ALL actions.

When you create a new property, always use Public property!
Public property names cannot contain lowercase letters.

Another solution would be to create a Spawn Dialog, with the remove option on it. Place a CA in install script which find in the registry after you product code which is already installed. Set a property if is found, and conditioned the dialog to appear with that condition. The dialog must be set before Maintenance Dialogs.
