如何在 Inno Setup 中获取卸载程序名称

Question

I have a project with different variants , which all install to the same location eg C:\\ABC\\ . Here the uninstallers are named unins000, unins001.. and so on. I have searched on net to changed the uninstaller names, and there is no inherent way to change the uninstaller name.

I have a workaround , by which I use the [Run] section to rename unins000.exe to the name of my choice. This works great on project folders when there will be only one uninstaller. However, in my case, the uninstaller name is not known to me.

Can someone suggest me a way to get the uninstaller name ? I will put the name accordingly in my code.

Please don't suggest me to look for timestamp. That will not be an acceptable solution.

Thanks in advance.

Answer 1

Inno Setup does not offer any way to let you name (or rename) the uninstaller.

Also note that when you rename the uninstaller manually (like you are doing), you break the reference to the uninstaller in the Add or remote application in Control Panel. Do not do that.

Another problem is that when you upgrade later, the new installer won't find logs of the previous installer and won't be able to merge them. Consequently a future uninstallation won't completely remove the application.
See the Appending to Existing Uninstall Logs in Inno Setup documentation.

The user should not uninstall the application by going to installation folder and executing the uninstaller. The user should go to Control Panel and select the application by its name.

Anyway, the uninstallers are numbered sequentially, so you can pick the uninstaller with the highest number.

I added the code below I used to achieve I wanted. Basically, what I am doing now is I create a seperate folder for each variant, where I store the individual uninstaller ( as I was not able to get the uninstaller which I will need to rename ) .

The project structure is now

C:\\ABC\\Uninst\\<Variant-1>\\<variant1-uninstaller> C:\\ABC\\Uninst\\<Variant-2>\\<variant2-uninstaller>

Add the [Run] section , this will change the uninstaller name to whatever is required. Also, registry entry in HKLM will be modified so that shortcuts and Control panel can uninstall the programs without any issues.

 `[Run]

  ;First rename the uninstaller files, then modify in registry
  ; /C : run CMD, execute command, then close the CMD.exe
  Filename: {cmd}; Parameters: "/C ren ""{app}\Uninst\unins000.exe"" ""Uninstall_{#ApplicationName}.exe"""; Flags: RunHidden WaitUntilTerminated

 Filename: {cmd}; Parameters: "/C ren ""{app}\Uninst\unins000.dat"" ""Uninstall_{#ApplicationName}.dat"""; Flags:  RunHidden WaitUntilTerminated

 ; REG ADD [ROOT\]RegKey /v ValueName [/t DataType] [/S Separator] [/d Data] [/f]
 ; /F : Force overwrite
 Filename: REG; Parameters: "ADD ""HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{#AppNameInReg}_is1"" /V ""UninstallString"" /T ""REG_SZ"" /D ""\""{app}\Uninst\Uninstall_{#ApplicationName}.exe"""" /F"; StatusMsg: Flags: RunHidden WaitUntilTerminated

 Filename: REG; Parameters: "ADD ""HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{#AppNameInReg}_is1"" /V ""QuietUninstallString"" /T ""REG_SZ"" /D ""\""{app}\Uninst\Uninstall_{#ApplicationName}.exe /SILENT"""" /F"; Flags: RunHidden WaitUntilTerminated

Add the following line in [Setup] section UninstallFilesDir={app}\\Uninst\\ This will create unins000.exe in Uninst folder.

Please note that I have solved my issue. I posted my code for any one who want to do similiar things.
