To launch a 64-bit PowerShell from a 32-bit cmd.exe, you can use the following command:
%SystemRoot%\sysnative\WindowsPowerShell\v1.0\powershell.exe
This command accesses the 64-bit version of PowerShell by using the sysnative alias, which redirects to the actual system32 directory on 64-bit systems. This allows you to run the 64-bit version of PowerShell from a 32-bit command prompt.
Keep in mind that some cmd.exe scripts or batch files may not work as expected when using this method, so it's important to test thoroughly before integrating it into your workflow.
What is the command to switch back to 32-bit PowerShell from 64-bit mode?
To switch back to 32-bit PowerShell from 64-bit mode, you can use the following command:
cd $env:windir\syswow64\WindowsPowerShell\v1.0 .\powershell.exe
This will change the directory to the 32-bit PowerShell executable and then launch the 32-bit version of PowerShell.

How to avoid common pitfalls when launching 64-bit PowerShell from 32-bit cmd.exe?
When launching 64-bit PowerShell from a 32-bit cmd.exe, there are some common pitfalls to avoid. Here are some tips to help you navigate this process successfully:
- Ensure that you are launching the correct version of PowerShell. When using a 32-bit cmd.exe to launch a 64-bit PowerShell, you need to explicitly specify the full path to the 64-bit version of PowerShell. You can usually find this at C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe.
- Be mindful of the environment variables. When using a 32-bit cmd.exe, the PATH variable may point to the 32-bit version of PowerShell. Make sure to use the full path to the 64-bit version of PowerShell in your command to avoid any confusion.
- Keep in mind potential compatibility issues. Some modules or scripts that work in 32-bit PowerShell may not function correctly in the 64-bit version. Make sure to test your scripts and modules in the 64-bit environment to ensure they work as expected.
- Understand the differences between 32-bit and 64-bit PowerShell. The 64-bit version of PowerShell can handle larger amounts of memory and can be more efficient with certain tasks. Familiarize yourself with the differences so that you can take full advantage of the capabilities of the 64-bit version.
By following these tips, you can avoid common pitfalls and successfully launch and use the 64-bit version of PowerShell from a 32-bit cmd.exe.
