我如何构造我的Inno Setup脚本自动注册一个dll,如果它是用户第一次安装我的应用程序,但取消注册以前的版本,如果有一个,然后注册新的(假设界面是不同的)?
我目前在我的文件部分使用regserver和ignoreversion标志,如下所示:
[Setup]
...
[Languages]
...
[Files]
Source: "C:example.dll"; DestDir: "{app}"; Flags: ignoreversion regserver
在我的谷歌搜索中,我发现了UnregisterServer,但我不知道如何将其添加到我的脚本。我很乐意开始修修补补,看看这是如何工作的,但我不想做任何会搞砸我的注册表。
这里有一个类似的帖子,但它没有说明这实际上是如何实现的。

在Pascal中破解后,我能够将以下内容添加到[Code]部分并且它工作了。有没有人知道如何使用{app}常量来动态定义下面代码中的fileName ?
[Code]
const
fileName = 'C:Program FilesTFolderNametigercontroller.dll';
var
serverExists: Boolean;
function InitializeSetup(): Boolean;
begin
serverExists := UnregisterServer(False, fileName, False);
if serverExists then begin
Result:= True;
MsgBox('This will update with the most recent version', mbInformation, mb_Ok);
end else
Result := True;
end;
如何使用BeforeInstall和AfterInstall参数文件?
用法是:
[Files]
Source: "MYDLL.DLL"; DestDir: "{app}"; BeforeInstall: MyBeforeInstall; AfterInstall: MyAfterInstall;
BeforeInstall和AfterInstall函数不能有返回值!
procedure MyBeforeInstall();
begin
// Your code here: If file (old) file exists call UnregisterServer() on old file
// Use function FileExists(const Name: String): Boolean; or similar for it
// Also you can delete the file entirely with function DeleteFile(const FileName: string): Boolean;
// Hint: You can use 'CurrentFileName' variable to get currently processed file
end;
procedure MyAfterInstall();
begin
// Your (new) file was processed and now you can do additional tweaks on it
// 'CurrentFileName' variable is still available
// Setup registers all files with the 'regserver' or 'regtypelib' flags as the last step of installation so in this function the file is still not registered!
end;
试试这个,它也可以处理32/64位并行COM服务器:
function UnregisterCOMServer(sServerCLSID: String): Boolean;varsServerPath:字符串;开始结果:= False;//在HKCR中搜索(合并视图)如果RegQueryStringValue(HKEY_CLASSES_ROOT, 'CLSID'+sServerCLSID+'InprocServer32', ', sServerPath)然后开始如果sServerPath<> "则开始日志('找到COM服务器CLSID:'+ sServerCLSID +',路径:'+sServerPath);结果:=UnregisterServer(False, sServerPath, True);if Result then Log('COM server '+ sServerCLSID +' unregistered.')else Log('UnregisterServer on '+ sServerPath +' failed!');结束else Log('没有找到COM服务器路径');结束else Log('COM server CLSID:'+ sServerCLSID +' not found!'+sServerPath);if Is64BitInstallMode then Begin if RegQueryStringValue(HKEY_CLASSES_ROOT, 'Wow6432NodeCLSID'+sServerCLSID+'InprocServer32', '', sServerPath) then Begin if sServerPath<>'' then Begin Log('Found COM server (Wow6432) CLSID:'+ sServerCLSID +', path:'+sServerPath); Result:=UnregisterServer(True, sServerPath, True); if Result then Log('COM server (Wow6432) '+ sServerCLSID +' unregistered.') else Log('UnregisterServer (Wow6432) on '+ sServerPath +' failed!'); end else Log('No COM server (Wow6432) path found.'); end else Log('COM server (Wow6432) CLSID:'+ sServerCLSID +' not found!'+sServerPath); end;
