问题 In [Components] I have two components (say A and B) defined exclusive . In fact the two components are not really components but two versions of the application configuration the user must choose from. Assume the user has installed my application with component A chosen. If the user installs an update of my application this time choosing component B a warning box pops up that says Setup has detected that the following components are already installed on your .... Deselecting these components

问题 I'm wanting to do a basic string validation within an Inno Setup script to be relatively certain the string is an email address. I just want to see that there is a '@' character followed by a '.' character and that there is at least one character on either side of these. Something similar to this regular expression: [^@]+@.+\.[^\.] The lack of regular expressions and limited string functions available in object pascal are causing me grief. It would be simple enough to reverse the string, find

I didn't call CheckGetFile() when installing...and it didn't call GetFilePath() and CheckGetFile() when Uninstalling..WHY?

问题 I have a need to retrieve a path to be used for some stuffs in the installer according an other application previously installed on the system. This previous application hosts a service and only provides one registry key/value hosting this information: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\APPLICATION hosting the value ImagePath which Data is "E:\TestingDir\Filename.exe" . I need a way to only extract the installation path ( E:\TestingDir ) without the Filename.exe file. Any

问题 I want to create a package for my Java application. The application has a GUI. I am confused about the difference between the Inno Setup and the Launch4j. My main question is does Inno Setup also create an .exe file like the Launch4j? Or do I need to create the .exe file with Launch4j and package the application with the Inno Setup? 回答1: Inno setup output is an installer as it is an installer maker. In the other hand launch4j is a wrapper to convert a jar into a exe. So if you want to

问题 I would like to be able to structure my code for my Inno Setup project but I am forced to move code around because you can't call a function unless it is defined first. Is there a way to declare a prototype at the top so that I don't get the "Unknown identifier" error and so that I can structure my code in logical blocks. 回答1: In Pascal (including a Pascal Script used in Inno Setup), you can define a function prototype (aka forward declaration) using a forward keyword: procedure ProcA(ParamA:

问题 I install some sample documents into a 'PerfectTablePlan' sub-folder of the standard 'My documents' folder on Windows. This works fine for 99%+ of users. But if a user doesn't have a 'My documents' folder I get a number of ugly error messages of the form: Internal error:Failed to expand shell folder constant “userdocs” This is not very confidence inspiring for the user! It is acceptable to not install the samples for these users (or install them somewhere else). But not to show the ugly error

问题 An installer I'm working on does most of its work in the PrepareToInstall function, as everything I need to do might fail, and therefore this is the appropriate place to handle these things in case they do fail. Any failure can be automatically reported by passing the error message in the function's result. There are only 3 small files which the installer actually copies over. The problem is that the wizard seems to freeze (or not respond rather) during this function, just showing a blank
