How to determine if an .exe file is 32-bit or 64-bit? If you have Windows 10 64-bit installed, you can run both 32-bit and 64-bit apps. However, you can run only 32-bit programs on Windows 10 32-bit installation. Here are a couple of ways to find out if a program is 32-bit or 64-bit on Windows 10.

Method 1: Check if a Program is 32-bit or 64-bit Using Task Manager

1. Launch the target program you want to check if it’s 32-bit or 64-bit, then open Task Manager and go to the Details tab. Right-click on a column header and choose Select columns.

   

2. Check the Platform box, and click OK.

   

3. Under the Platform column, you can easily see if a particular program on you system is 32-bit or 64-bit.

   

Method 2: Check if a Program is 32-bit or 64-bit via Compatibility

1. Find the launcher file (*.exe) of a program whose architecture you want to find out, then right-click on it and select Properties.
2. Go to the Compatibility tab, check the “Run this program in compatibility mode for” option and click the drop-down list. If your list starts with “Windows Vista“, then your program is 64-bit. If the list starts with “Windows 95” then your app is 32 bit.

   

Method 3: Check if a Program is 32-bit or 64-bit Using Command Prompt

1. To get started, download the free command-line utility called SigCheck from Microsoft Sysinternals. The download is a 799 KB ZIP file. After extracting, go to the extracted folder and open an elevated Command Prompt window.
2. Type the following command and hit Enter. Remember to specify the full path to your target executable file.
   sigcheck.exe "full-path-to-EXE"
3. At the right end of the output, a line called “MachineType” will tell you if the EXE is 32-bit or 64-bit.

   

That’s it!
