OnUpdateUIBefore on installscript msi

[shlomi]

I want to create an installscript msi project but use scripts that I have from installscript projects.
but I get error like OnUpdateUIBefore functions has no prototype
How can I solve this issue?

You need to declare your function

just add the following line, either at the top of your implementation (.RUL) file, or in the corresponding header (.H) file.

prototype OnUpdateUIBefore();

When you work in an Installscript project, this function is already pre-declared. But that's not the case in an MSI project.

For a minor upgrade in an InstallScript MSI project, perhaps see if OnResumeUIBefore does what you want.
