推荐答案

Seki 的回答大部分是正确的，我只想补充一点，Exec/ExecWait 的正确语法是always Exec '"c:\path\app.exe" param1 "par am2" param3'

The answer from Seki is mostly correct, I'd just like to add that the correct syntax for Exec/ExecWait is always Exec '"c:\path\app.exe" param1 "par am2" param3'

参数当然是可选的，但应用程序的路径应该总是被引用，不仅仅是因为在你的情况下 $INSTDIR 可能包含空格但至少在 Win9x 上它会失败，如果你不引用(根据到 NSIS 手册)

Parameters are of course optional but the path to the app should always be quoted, not just because in your case where $INSTDIR could contain spaces but at least on Win9x it will fail no matter what if you don't quote (According to the NSIS manual)

如果空格/缺少引号不是问题，那么您可能还需要研究其他几件事:

If the spaces/lack of quotes is not the issue then there are a couple of other things you might want to look into:

• $OUTDIR 是新进程的工作目录(SetOutPath 设置)
• 缺少 dll 等(检查 进程监视器)
