Similar(or Exact) question and long discussion here: Last accessed date and time of all the installed software[^]

You can interact with the answerer there if needed.

Also, look at the following link: How to Get and Set file Last Access Time and Date using System.io in c# (.net 2.0).[^]

Thanks for your help
I think your answer is for files and folders I do not want to get last access date for files and folders. I need the last access date for installed software.

Ah, that was my answer. My 5 (I cannot disavow my own answer, can I? :-)

Solution 2

Take a look at Windows Management Instrumentation WMI Tasks: Computer Software[^]

And make at WMI query with "Select * from Win32_Product"

WqlObjectQuery wqlQuery = new WqlObjectQuery("SELECT * FROM Win32_Product");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(wqlQuery);
foreach (ManagementObject row in searcher.Get())
{
  object name = row["Name"];
  object version = row["Version"];
  Console.WriteLine("Name: " + name + " - Version: " + version);
}

Thanks for Helping.
What you have said is correct but I does not show all the installed software list. For example It does not show for Microsoft word,power point, Excel. I need to get all the installed software with last access date.

I have also used WMI to query the installed software list. But It does not give all the installed software.

Perhaps not all programs are installed using Microsoft Installer (MSI). Here at my computer, Microsoft Office suite is listed: Word, Excel etc.

sacraj 26-Apr-11 7:03am

I shall again check this code on my Computer. Can not I get the list of installed software which are not installed using MSI(Microsoft Installer).

Sergey Alexandrovich Kryukov 26-Apr-11 15:54pm

I think this is a better answer than mine (in Sandeep's reference, please see). My 5.
