如何在不使用注册表的情况下确定Acrobat Reader版本

Question

I know that Acrobat reader is installed,but i wanna know that which version of acrobat installed? But without using Registry key. There is any Acrobat reader function for getting it?

Thanks in advance

I used following Code but its throw exception at some places

RegistryKey adobe = Registry.LocalMachine.OpenSubKey("Software").OpenSubKey("Adobe");
        if (adobe != null)
        {
            RegistryKey acroRead = adobe.OpenSubKey("Acrobat Reader");
            if (acroRead != null)
            {
                string[] acroReadVersions = acroRead.GetSubKeyNames();

                string versionNos = "";
                string ResultAcrobat ="";
                foreach (string versionNumber in acroReadVersions)
                {
                    if (Convert.ToDecimal(versionNumber) >= 9)
                    {
                        ResultAcrobat = "OK";
                    }
                    versionNos += ",Version v" + versionNumber;
                }
                versionNos = versionNos.Remove(0, 1);
                AcrobatReader = versionNos;

                if (Convert.ToString(dr["ResultAcrobat"]) == "")
                {
                    ResultAcrobat = "Error";

                }

            }

Sure, but it is more hackish than reading the registry (which holds the actual application being opened).

My suggestion if you can't read the registry is this:

• Find all files names AcroRd32.exe in the program files folder, in my case under C:\\Program Files (x86)\\Adobe ;

• Get the file version from the executables found using this code:

   string[] files = Directory.GetFiles(@"C:\\Program Files (x86)\\Adobe", "AcroRd32.exe", SearchOption.AllDirectories); // determine which one to use string pathToAdobeExe = files.First(); string version = FileVersionInfo.GetVersionInfo(pathToAdobeExe).ProductVersion;
