问题:

I'm trying to build an NSIS installer that will do the following:

1 When run normaly it will install the application with a installer with the usual choices.

2 When the installer is run with /S switch it silent installs, it's ok if it shows UI. But it should be automatic.

It seems to me that the installer "works", as it runs and then correctly starts the application again. But it has not updated anything, it's almost as if it runs, but does not copy any files.

When it's a silent install, it's started by the following code ( Application updates itself)

    ProcessStartInfo Pro = new ProcessStartInfo();     Pro.Verb = "runas";     Pro.UseShellExecute = true;     Pro.FileName = gDownloadedFileName;     Pro.Arguments = "/S";     Pro.WindowStyle = ProcessWindowStyle.Normal;     Pro.CreateNoWindow = true;

NSIS script main ( I can post support scripts for NSIS that are custom if ppl desire )

回答1:

StrCmp $0 1 0 +3 is wrong, it should be +2 (+3 in this example is probably undefined behavior since you are skipping the hidden return instruction).

Using relative jumps is error prone, you should use a label or rewrite it using the logic lib:

!include LogicLib.nsh ... Function .onInit   Call GetDotNet    ${If} ${Silent}     call SilentInstall   ${EndIf} FunctionEnd

But putting the silent install logic in a separate function doubles your work when the normal install logic is almost equal. You should be able to remove the SilentInstall function and just use a hidden section to execute during silent installs:

Section "${_AppName} (required)" #shared install code SectionEnd  Section "Start Menu Shortcuts" #shared startmenu code SectionEnd  Section ${If} ${Silent}     Exec ${_AppExe} ${EndIf} Section

It is hard to say why your files are not updated, but if you use shared code you can run it without /S and check the detail log. My only guess is that InstallDirRegKey is picking up a non default installdir and you are looking at the wrong files. You can Process Monitor to monitor the install.

Your code has some other unrelated issues:

RequestExecutionLevel admin is not enough, you need to deal with NT5 and NT6 with UAC off (UserInfo::GetAccountType)
You don't have to specify the shortcut icon when the icon is the same as the target program
You should quote the path when calling Exec: Exec '"$instdir\${_AppExe}"'
Mixing UAC/runas/RequestExecutionLevel admin with Exec is problematic since you can end up running the program as the wrong user.

回答2:

This is a tricky one. I am using the same approach to update an application of mine, calling an NSIS installer silently. In my case, the problem did not lie in the NSIS script, it was that I was using the WebClient class to download a zip file containing my installer to the temp directory, and subsequently extracting it there, and running it from there. The problem is that the ZipFile class generates an exception if the extracted setup file exists, and hence the old installer persists, and nothing except the uninstall executable is updated in the program directory.

For me, the solution was to clean up the old zip and exe files before downloading the new ones (in VB.NET):

    If File.Exists(Path.Combine(Path.GetTempPath(), "Setup.zip")) Then         File.Delete(Path.Combine(Path.GetTempPath(), "Setup.zip"))     End If     If File.Exists(Path.Combine(Path.GetTempPath(), "Setup.exe")) Then         File.Delete(Path.Combine(Path.GetTempPath(), "Setup.exe"))     End If
