    if(RegDBKeyExist (szKey) >=1) then          
        MessageBox("Key found", INFORMATION);       

    if(RegDBGetKeyValueEx(szKey, szName, nvType, svValue, nvSize) < 0) then
        MessageBox("Failed to get value", INFORMATION);
    else

RegDBSetDefaultRoot(HKEY_CLASSES_ROOT);                 
end;

推荐答案

Installscipt :您的价值所在何处?您是否考虑了注册表的64-与32 bit部分?

• HKEY_LOCAL_MACHINE\SOFTWARE

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

可能要调查如果您需要注册表的64位部分，请点击此处的64位选项 (REGDB_OPTION_WOW64_64KEY).

AppSearch :对于这样的简单注册表检索，您可以使用系统搜索视图/向导.

AppSearch: for a simple registry retrieval like this, you could use AppSearch instead (System Search View). I don't have the time to make a sample for that right now. You can also see the System Search View / Wizard.
