<div>
there are number of ways to detect that, here's one:<br />
if the following registry is exists than it is 64bit, otherwise it's 32bit.<br />
<br />
HKEY_LOCAL_MACHINE\SOFTWAR<wbr />E\Wow6432N<wbr />ode<br />
<br />
so in your vb.net code use the following:<br />
<br />
Dim is64bit As Boolean = Registry.LocalMachine.Open<wbr />SubKey(&quot;SO<wbr />FTWARE\Wow<wbr />6432Node&quot;)<wbr /> IsNot Nothing<br />
<br />

</div>

if the following registry is exists than it is 64bit, otherwise it's 32bit.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

so in your vb.net code use the following:

Dim is64bit As Boolean = Registry.LocalMachine.OpenSubKey("SOFTWARE\Wow6432Node") IsNot Nothing



<div>
another way is using WMI:<br />
<br />
Dim mso As New ManagementObjectSearcher(&quot;<wbr />SELECT *FROM Win32_OperatingSystem&quot;)<br />
Dim qc As ManagementObjectCollection<wbr /> = mso.[Get]()<br />
For Each mo As var In qc<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dim ostype As String = mo(&quot;OSArchitecture&quot;).ToStr<wbr />ing()<br />
Next<br />
<br />
the value of ostype is: &quot;64-bit&quot; or &quot;32-bit&quot;
</div>


another way is using WMI:

Dim mso As New ManagementObjectSearcher("SELECT *FROM Win32_OperatingSystem")
Dim qc As ManagementObjectCollection = mso.[Get]()
For Each mo As var In qc
      Dim ostype As String = mo("OSArchitecture").ToString()
Next

the value of ostype is: "64-bit" or "32-bit"

How can I automatically determine (through code, under the setup deployment) which platform the user is running and then run the correct install program?

VS.Net Setup Project - 32 and 64 bit

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
