From TechNet article on 64-bit editions of Office 2010: If you have installed Office 2010 including Microsoft Outlook 2010, Outlook sets a registry key named Bitness of type REG_SZ on the computer on which it is installed. The Bitness registry key indicates whether the Outlook 2010 installation is 32-bit or 64-bit. This may be useful … Read more
On an x64 machine, here is an example of how to access the 32-bit view of the registry: using (var view32 = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry32)) { using (var clsid32 = view32.OpenSubKey(@”Software\Classes\CLSID\”, false)) { // actually accessing Wow6432Node } } … as compared to… using (var view64 = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64)) { using (var clsid64 = view64.OpenSubKey(@”Software\Classes\CLSID\”, true)) … Read more
To manually review, you can use the regedit.exe application to load the privateregistry.bin file by doing the following: Launch RegEdit.exe Select the Computer\HKEY_LOCAL_MACHINE node in the left-hand pane Select the File | Load Hive… menu item, and load the privateregistry.bin When prompted for a key name, just type in something like “VSRegHive” This will load … Read more
Open the registry : RegOpenKeyEx Query the value : RegQueryValueEx /* do something with value*/ Set the value back : RegSetValueEx close the registry : RegCloseKey
Documentation says that EnumKey returns string with key’s name. You have to explicitly open it with _winreg.OpenKey function. I’ve fixed your code snippet: from _winreg import * aKey = r”SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall” aReg = ConnectRegistry(None, HKEY_LOCAL_MACHINE) print(r”*** Reading from %s ***” % aKey) aKey = OpenKey(aReg, aKey) for i in range(1024): try: asubkey_name = EnumKey(aKey, i) asubkey … Read more
You need to first add using Microsoft.Win32; to your code page. Then you can begin to use the Registry classes: try { using (RegistryKey key = Registry.LocalMachine.OpenSubKey(“Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net”)) { if (key != null) { Object o = key.GetValue(“Version”); if (o != null) { Version version = new Version(o as String); //”as” because it’s REG_SZ…otherwise … Read more
Active Setup is no longer advisable (original source). There are several ways to achieve what you want – one clunkier than the other. Terminal servers can be a deployment nightmare – users may not have rights to run msiexec.exe and hence MSI self-repair could fail. That’s why I generally prefer to use batch files, scripts … Read more
With .NET API you can read 64-bit values like this: $key = [Microsoft.Win32.RegistryKey]::OpenBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine, [Microsoft.Win32.RegistryView]::Registry64) $subKey = $key.OpenSubKey(“SOFTWARE\Microsoft\.NETFramework”) $root = $subKey.GetValue(“InstallRoot”)
After searching and troubleshooting, I got it to work this way: public static bool checkInstalled (string c_name) { string displayName; string registryKey = @”SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall”; RegistryKey key = Registry.LocalMachine.OpenSubKey(registryKey); if (key != null) { foreach (RegistryKey subkey in key.GetSubKeyNames().Select(keyName => key.OpenSubKey(keyName))) { displayName = subkey.GetValue(“DisplayName”) as string; if (displayName != null && displayName.Contains(c_name)) { return true; … Read more
For brevity, I’m using a fake root key. In practice, replace Hive_Key with HKEY_LOCAL_MACHINE for system default settings, or HKEY_CURRENT_USER for per-user settings. Either of these keys are allowed to exist, or both. If they both exist, the HKCU key takes precedence. To associate an extension with a file type, you need to set the … Read more
