I have create Installer in 5.0.0 with following specification :
In Bootsrapper Tab
"Create EXE setup file" option checked
Under Package ,"Leave Install files outside" option selected
I have select option that remove MSI file after installation.
Now I have create patch in 5.1.1 for that. Both target MSI and Update MSI is created in 5.0.0.
But when i am going to install patch on client machine ,its going to search old MSI file.
Zaki..
