Uninstall Survey for Inno Setup

  With Uninstall Survey (IssSurvey.dll extension) for Inno Setup you can get users feedback / comments / uninstall reasons by presenting a quick survey when your product is about to be uninstalled. It is true that most of the users will click right past it, but a small number will give you some feedback that maybe will help you improve the product. You may not get a lot of quality information with uninstall survey, but you may well find one "gem" that will make a big difference in sales/quality - something your software maybe is missing, for example.

Features:

• easy to use
• small size (only 25KB)

• multi-language support (text infos and reasons template are fully customizable)
• user feedback it is sent by a POST to a php script on the application/publisher home page. A user name and password can also be sent for more security. (php scripts examples included)
• what to do with the user feedback is up to you. You can either make the php script to send the comments/feedback in your mail inbox or save it in a local file on your server or in a database.
• uses the standard Windows Internet API (wininet.dll) for internet connection meaning that there is no need for a proxy configuration as long as IE (Internet Explorer) is configured
• 100% free

11. //
12. //  ReasonsList  = Uninstall reasons templates list. Separate multiple reasons with semicolon.
13. //                 Set this value to empty string '' to hide the template reasons combo box and show only the edit box

19. //                $pass      = the password you pass on the IssSurvey Extension function (for security purpose)
20. //                $cntinfo   = the user reason/comments/feedback. !!Warning: the sent text is base64 encoded.
21. //                $IssSurvey = just for a check control. It will be set to 1 by IssSurvey Extension
22. //
23. //  UserName   =  a user name to submit along with the reason/comments  (for security purpose)
24. //
25. //  Password   =  a password to submit along with the reason/comments  (for security purpose)
26. //
27. //******************************************************************************************************************************************
28.  
29.  
30. function InitializeUninstall(): Boolean;
31. var
32.   sReasons: String;
33.   nCode: Integer;  { 0 if the user has submited the comments; 1 if cancel or close pressed; 2 if ignore/skip pressed; -1 if an error occured }
34.  
35. begin
36.      Result   := false;
37.      sReasons := 'I do not understand how to use this product;I like the product but do not want to pay for it;I was bothered by the sponsored links;Other reason (see below):';
38.      nCode    := IssSurvey('en',sReasons,'http://raz-soft.com/IssSurvey/IssSurvey_mail.php','demo','demo');
39.  
40.      if (nCode=0) or (nCode=2) then begin                    { submited or ignored }
41.           Result := true;                                    { continue uninstall setup      }
42.      end;
43.  
44.     // Unload the extension, otherwise it will not be deleted by the uninstaller
45.     UnloadDLL(ExpandConstant('{app}\IssSurvey.dll'));
46.  
47. end;

4. Set sReasons from the above code with your own reasons list (separate multiple reasons with semicolon). If sReasons is empty the reasons template combo box will be removed.
5. Compile and test your setup. Before Inno will begin uninstall operation IssSurvey will popup with a window asking the user if he wants to give some feedback/comments. The user can choose to Ignore this and continue with the uninstall process or he can submit a quick comment/feedback before uninstalling.

Note: in the above demo the user feedback will be sent to my tested script: http://raz-soft.com/IssSurvey/IssSurvey_mail.php please replace this address with your own and also edit the script IssSurvey_mail.php so that it will send the feedback to your inbox and not mine.

If you're testing with my demo script/setup please include your e-mail address in the survey text box and I will reply you the feedback/survey text received from IssSurvey. You can also test the setup with the second php script (located here ) The info you enter in the survey will be saved in a local file on my server and it will also be listed if you access the script directly here .
