Question

My application currently installs documents and other files to two folders using lines like:

Source ... DestDir: {userdocs}\{#MyAppName}\Layouts
Source ... DestDir: {userappdata}\{#MyAppName}

Up until now I have not accommodated the need some users in classrooms have to install the software logged in as one (admin) user, but then have students use the software logged into a student account.

I have just created some code that uses CreateInputOptionPage to create a custom wizard page that asks the user whether to install to documents to the current user or all users.

How do I use the results of my new custom wizard page to control the two Source lines above. Rather than {userdocs} and {userappdata} above, depending on the value of Page.Values[0], I want to use {commondocs} and {commonappdata}. (Is my thinking correct about using the common folders?)

Can I create some sort of runtime variable I can use in the Source lines, or an IFDEF variable?

Does iss have other built-in functionality to help me in this area?

Answer 1

You can use the Check parameter. The check would refer to a function that would return a boolean value, if the return is ‘true’ then the entry is processed, otherwise it won’t be.

Source ... DestDir: {userdocs}\{#MyAppName}\Layouts; Check: not IsAllUsers
Source ... DestDir: {commondocs}\{#MyAppName}\Layouts; Check: IsAllUsers

[Code]
...

function IsAllUsers: Boolean;
begin
  Result := Page.Values[0] = ...
end;
