InstallAware

I read in the manual that I can specify this on the Dialogs Page. But unfortunatly I cannot found the option in User Interface > Dialogs .

I have InstallAware 9 Studio.

Can I change this maintenance behaviour somehow in the Design or MSICode View?

One of the ways you could do this is to modify the dialogs / logic so the user is not prompted to choose between change and remove. Also, modify the registry for Add/Remove Programs entry, adding the NoModify / NoRepair entries.

Thank you eugen, my friend.

I tried but it didn't help...I added the entries

"NoModify"=dword:00000001
"NoRepair"=dword:00000001

in

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\<myApp>]

I now tried the installshield way: Uninstall Shortcut that points to msiexec with argument /X $PRODUCTCODE$ but then the source is not found.

I will try further...

I now created a new project for my product and selected in the project wizard the option "I prefer to provide an uninstall option only".

I got the code for maintenance:

label: Maintenance
Comment: Maintenance Install/Uninstall
Set Variable UNINSTALL to YES
MessageBox: $TITLE$ Uninstall, Are you sure you want to uninstall the selected application and all of its components?
if Variable UNINSTALL Equals NO
Terminate Installation
else
Set Variable REMOVE to TRUE
end

I pasted this code in my standard project and now it works as desired.
Would be easier if you could choose this option also if the project wizard is already finished.
