I know how to have Inno Setup create/manipulate registry keys and/or values on install and I know that you can delete a value, a key, etc when uninstalling. But is there any way to have Inno Setup actually change the value of a key when the uninstall process is done?
The setup I'm creating changes the value of a dword key that another application uses to a value to 1, indicating it's installed, and when this application is removed I need the value to be restored to 0, indicating it's removal. Is this possible, without deleting the actual key/value?
You can use specific RegWrite
function (for DWord
, Binary
, StringValue
, etc) in procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
with usPostUninstall
or usDone
procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
begin
if CurUninstallStep = usPostUninstall then
RegWriteStringValue(HKEY_CURRENT_USER, 'Software\My Company\My Program',
'UserName', ExpandConstant('{sysuserinfoname}'));
end;
