32位NSIS是否可以启动64位程序？

Question

I'm porting a windows program from 32 -> 64 bit. It has a 32 bit installer which is written using NSIS. Can I launch one of my new 64 bit exes using the 32 bit NSIS installer? I don't think there is a 64 bit version of NSIS...

Answer 1

Sure you can, NSIS doesn't impose any restrictions and what's really nifty about NSIS is if you have both 32 and 64 bit versions of your app, you can do a combined installer, and install the required files on a per-architecture basis. eg

!include "x64.nsh"

${If} ${RunningX64}
    File ..\x64\blah.exe
${Else}
    File ..\x86\blah.exe
${EndIf}

Answer 2

NSIS使用两个Win32 API来执行ShellExecute （通过ExecShell ）和CreateProcess （通过Exec和ExecWait ）进程，它们都可以从NSIS 32位进程运行64位进程（x64）（只要你在64位操作系统上运行） ）。

Answer 3

For executing processes needing 64-bit operation I found the default NSIS execution would not automatically run in 64-bit mode. I encountered this when trying to run DISM to install .NET Framework 3.5. DISM would error out stating:

"You cannot service a running 64-bit operating system with a 32-bit version of DISM."

To resolve I added needed to add DisableX64FSRedirection before the call that needs 64-bit operation. See below for example:

${If} ${RunningX64}
   ${DisableX64FSRedirection}
   DetailPrint "Disabling Windows 64-bit file system redirection"
${EndIf}

nsExec::ExecToStack 'Dism.exe /Online /Enable-Feature /FeatureName:NetFx3'

${If} ${RunningX64}
   ${EnableX64FSRedirection}
   DetailPrint "Re-enabling Windows 64-bit file system redirection"
${EndIf}

Well.. there are some restrictions here.. for instance, try run odbcconf.exe to install a driver. I have not been able to figure out a way to make that come in as a 64bit entry. Same way I think as if you (in a 64bit system) start "powershell x86" as admin, then run cmd and odbcconf from there - no easy way to get around it that I can find, making odbcconf do x64
