Here are some common approaches:<\/p>\n\n\n\n<p><strong>File Properties<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Windows Explorer<\/strong>: Right-click on the DLL file, select &#8220;Properties,&#8221; and go to the &#8220;Details&#8221; tab. Look for the &#8220;File version&#8221; and &#8220;Product version&#8221; fields. Typically, 32-bit DLLs will have &#8220;x86&#8221; or &#8220;32-bit&#8221; mentioned, while 64-bit DLLs will have &#8220;x64&#8221; or &#8220;64-bit&#8221; in these fields.<\/li>\n\n\n\n<li><strong>Command Prompt<\/strong>: You can use the <code>file<\/code> command in the Command Prompt to check the file type.

A value of <code>0x14C<\/code> indicates 32-bit (x86), while <code>0x8664<\/code> indicates 64-bit (x64).<\/li>\n\n\n\n<li>Alternatively, you can use the <code>objdump<\/code> utility if you have it installed: <\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:&quot;language&quot;,&quot;fullScreenButton&quot;:true,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;shell&quot;,&quot;mime&quot;:&quot;text\/x-sh&quot;,&quot;theme&quot;:&quot;material&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:false,&quot;readOnly&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;Shell&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;shell&quot;}\">objdump -p path_to_your.dll | grep &quot;machine&quot;<\/pre><\/div>\n\n\n\n<p><strong>Programming Languages<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If you&#8217;re working with a programming language like C# or .NET, you can use code to check the architecture of an assembly or DLL.
