(5.2.2) Can not Disable Cancel button in uninstall dialog

[rosen.nedialkov]

Hello, I have the following problem. I can not disable the cancel button while uninstalling my product. I badly need this because I use many custom actions in dlls while installing/uninstalling. I had disabled the Cancel button while installing but cannot find a way to do it while uninstalling.

Hi,

Disabling the Cancel button is not possible during an uninstall, but you can hide it, using a VBScript or C++ DLL Custom Action. For example, you can add the following VBScript CA under "InstallExecuteSequence -> Begin" (or before your first Custom Action):

Code: Select all

Function HideCancelButton()
  Dim Record
  Const msiMessageTypeCommonData = &H0B000000
  Set Record = Installer.CreateRecord(2)
  Record.IntegerData(1) = 2
  Record.IntegerData(2) = 0
  Session.Message msiMessageTypeCommonData, Record
 
  ' return success
  HideCancelButton = 1
  Exit Function
End Function

Hope this helps.
