Question

执行/运行以下Inno代码，我收到错误消息。文件“ c：\ xxxx-runtime \ unins000.exe”确实存在。

错误消息：

Unable to execute file:
"c:\xxxx-runtime\unins000.exe"
CreateProcess failed; code 267.
The directory name is invalid.

下面显示的Inno代码：

[UninstallRun]
Filename: "{code:ARGetUninstallString}";
;Filename: {code:ARGetUninstallString};   -- same result

[Code]
function ARGetUninstallString(p: String): String;
var
  sUnInstPath: String;
  sUnInstallString: String;
begin
  sUnInstPath := ExpandConstant('Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\xxxx_is1');
  sUnInstallString := '';
  if not RegQueryStringValue(HKEY_LOCAL_MACHINE, sUnInstPath, 'UninstallString', sUnInstallString) then
    RegQueryStringValue(HKEY_CURRENT_USER, sUnInstPath, 'UninstallString', sUnInstallString);
  Result := sUnInstallString;
end;

但是，如果我更换

，它会很好地工作

[UninstallRun]
Filename: "{code:ARGetUninstallString}";

使用

[UninstallRun]
Filename: "c:\xxxx-runtime\unins000.exe";

是否有Inno专家知道问题所在？

Answer 1

您发现自己[Code]常数是在安装时评估的。

因此，请完全在[UninstallRun]部分中实现代码，而不要使用[Code] procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep); begin if CurUninstallStep = usPostUninstall { or usUninstall } then begin { Use RegQueryStringValue and Exec here } end; end;部分。

UninstallString

尽管您需要修复可解析卸载程序命令行的代码。注意在有关该主题的所有现有问题中，import os import glob import pandas as pd import numpy as np files = glob.glob('folder/*.csv') for file in files: file_name = os.path.splitext(os.path.basename(file)) # Get the file name without extension df = pd.read_csv(file) #make conversion df['Time taken'] = pd.to_datetime(df['Time taken']) df['Time taken'] = df['Time taken'].dt.hour + df['Time taken'].dt.minute / 60 #output file df.to_csv('{}_conv.csv'.format(file_name, index = False)是如何拆分为程序路径和参数的。由于程序路径用双引号引起来，因此需要将其删除。

Answer 2

以下是我的解决方案，在从reg获取路径之前，基本上在[code]部分中执行xxxxx-runtime.exe。以下是源代码：

[Files]              
Source: ".\xxxxx-runtime.exe"; DestDir: "{tmp}"; Flags: deleteafterinstall

[UninstallRun]
Filename: {code:GetUninstallString}; BeforeInstall: SetUninstallString; RunOnceId: {code:GetUninstallString}

[Code]
var
uninstallString: String;

function getUninstallString(p: String): String;
begin
  Result := uninstallString;
end;

// execute xxxxx-runtime.exe
procedure exe();
var
  iResultCode: Integer;
begin
  Exec(ExpandConstant('{tmp}\xxxxx-runtime.exe'), '/SILENT /NORESTART /SUPPRESSMSGBOXES','', SW_HIDE, ewWaitUntilTerminated, iResultCode);
end;

procedure SetUninstallString();
var
  sUnInstPath: String;
  sUnInstallString: String;
begin
  exe();
  sUnInstPath := ExpandConstant('Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\xxxxx_is1');
  sUnInstallString := '';
  if not RegQueryStringValue(HKEY_LOCAL_MACHINE, sUnInstPath, 'UninstallString', sUnInstallString) then
    RegQueryStringValue(HKEY_CURRENT_USER, sUnInstPath, 'UninstallString', sUnInstallString);
  uninstallString := RemoveQuotes(sUnInstallString);
end;

无效的问题：无法执行从RegQueryStringValue检索的文件
