请求编写32位PowerShell执行报错、仅支持64位的脚本

Here's a straightforward script that enforces execution only in 64-bit PowerShell, and throws a clear, actionable error if run in 32-bit:

# Detect the underlying PowerShell architecture
$ptrSize = [IntPtr]::Size

if ($ptrSize -eq 4) {
    # Throw a terminating error for 32-bit environments
    throw "Error: This script requires 64-bit PowerShell. Please launch the 64-bit version (usually located at `C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe`) and try again."
}
elseif ($ptrSize -eq 8) {
    # Your 64-bit-only script logic goes here
    Write-Host "Success: Running in 64-bit PowerShell. Executing main workflow..."
    
    # Example 64-bit specific operation (replace with your actual code)
    # Get-ItemProperty -Path "HKLM:\Software\Your64BitOnlyKey"
}
else {
    # Fallback for unexpected architecture scenarios
    throw "Error: Unsupported PowerShell architecture detected. This script only runs on 64-bit systems."
}

Key Details: #

• [IntPtr]::Size is a reliable way to detect architecture: it returns 4 for 32-bit processes and 8 for 64-bit processes.
• Using throw ensures the script stops immediately in 32-bit mode—no unintended partial execution.
• The error message includes a specific path to the 64-bit PowerShell executable to help users quickly resolve the issue.

Customization Tips: #

• Tweak the error message to match your script's purpose (e.g., mention specific 64-bit dependencies).
• Replace the example code in the 64-bit block with your actual workflow that requires 64-bit access.
