        "content": "Here\u2019s how you can uninstall **Microsoft AI Shell** installed via *winget*, and what the other installation method is (and how it works).\n\n---\n\n## 1. Winget Uninstall Command\n\nIf you installed AI Shell using winget, the official uninstall command is:\n\n```\nwinget uninstall --product-code Microsoft.AIShell_Microsoft.Winget.Source_8wekyb3d8bbwe\n```\n\n- The *product code* used above is `Microsoft.AIShell_Microsoft.Winget.Source_8wekyb3d8bbwe`. ([advanceduninstaller.com](https://www.advanceduninstaller.com/AI-Shell-4af70539ae16457bec301f6764c70c71-application.htm?utm_source=openai))  \n- This command targets the specific application installed via winget. You\u2019ll need to run this in a PowerShell or Command Prompt with administrator privileges. ([advanceduninstaller.com](https://www.advanceduninstaller.com/AI-Shell-4af70539ae16457bec301f6764c70c71-application.htm?utm_source=openai))\n\nYou could also sometimes uninstall by name or ID instead of product-code:\n\n```\nwinget uninstall Microsoft.AIShell\n```\n\nor using the exact ID:\n\n```\nwinget uninstall --id Microsoft.AIShell\n```\n\nThese often work if there isn\u2019t ambiguity among multiple products with similar names. ([learn.microsoft.com](https://learn.microsoft.com/en-us/%20%20windows/package-manager/winget/uninstall?utm_source=openai))\n\n---\n\n## 2. Other Installation Method\n\nThe other common method is installing AI Shell via a PowerShell script. Microsoft provides a script called **installaishell.ps1**. That script:\n\n- Installs the `aish.exe` executable (the AI Shell command-line shell) to ` %LOCALAPPDATA%\\Programs\\AIShell ` and adds it to your PATH on Windows. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))  \n- Also installs the **AIShell** PowerShell module. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n### How to Use It\n\n- To install via that method:  \n  ```powershell\n  Invoke-Expression \"& { $(Invoke-RestMethod 'https://aka.ms/installaishell.ps1') }\"\n  ```  \n  ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n- To uninstall when it was installed this way, you use the same script with the `-Uninstall` flag:\n\n  ```powershell\n  Invoke-Expression \"& { $(Invoke-RestMethod 'https://aka.ms/installaishell.ps1') }\" -Uninstall\n  ```\n\n  That removes both the executable and the module that were added via this method. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n---\n\n## 3. How to Know Which Method You Used\n\nTo determine which installation method you have (winget vs script), you can try:\n\n- Running the winget uninstall command. If winget reports that AI Shell (or the product-code) isn\u2019t installed, then probably you used the script instead.  \n- Checking if there\u2019s an executable at `%LOCALAPPDATA%\\Programs\\AIShell\\aish.exe`. If yes, likely the script install method.  \n- Checking PowerShell modules: `Get-Module -ListAvailable AIShell`. If this module is there, then the script method was used.  \n\n---\n\nIf you tell me which of these two commands gives you an error or what output you get, I can help you pick the correct method and even remove leftover bits."

        "content": "You're getting the error about the `var` keyword being unsupported because your PowerShell session is likely running a version *older* than what's required for AI Shell. The AI Shell install script explicitly requires **PowerShell 7.4.6 or newer**. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n---\n\n### \ud83d\udd0d Steps to check and fix this\n\n1. **Check your current PowerShell version**  \n   Run this in your PowerShell terminal:\n   ```powershell\n   $PSVersionTable.PSVersion\n   ```\n   You're looking for **Major = 7**, **Minor \u2265 4**, and **Patch \u2265 6**. If the version is something like `5.1.x` or `7.3.y`, that's too old. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n2. **Upgrade to PowerShell 7.4.6 or newer**  \n   You can do this via several methods:\n\n   - Using **winget**:\n     ```powershell\n     winget install Microsoft.PowerShell\n     ```\n     This typically gets you the latest stable version.  \n   - Downloading directly from the [PowerShell GitHub Releases page](https://github.com/PowerShell/PowerShell/releases).  \n   - Using the Microsoft Store which may install an auto-updating version.  \n   ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?azure-portal=true&view=powershell-7.5&utm_source=openai))\n\n3. **Confirm requirements for AI Shell**  \n   The official Microsoft Learn page for AI Shell states these system prerequisites on Windows:\n\n   - Windows 10 or higher  \n   - PowerShell **7.4.6 or higher**  \n   - PSReadLine version **2.4.2-beta2 or higher**  \n   ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/utility-modules/aishell/install-aishell?view=ps-modules&utm_source=openai))\n\n---\n\n### \u2705 After upgrading, try the install again\n\nOnce you have PowerShell 7.4.6 or newer:\n\n```powershell\nInvoke-Expression \"& { $(Invoke-RestMethod 'https://aka.ms/installaishell.ps1') }\"\n```\n\nIf you want to uninstall, run the same with the `-Uninstall` switch:\n\n```powershell\nInvoke-Expression \"& { $(Invoke-RestMethod 'https://aka.ms/installaishell.ps1') }\" -Uninstall\n```\n\n---\n\nIf you're not able\u2014or don\u2019t want\u2014to upgrade, I can help you modify the script so it works in your current PowerShell version (if possible), or suggest a fallback method. Do you want me to walk you through that?"

        "content": "If you're getting the \"var keyword is unsupported\" error *yet* you\u2019re running **PowerShell 7.6.4**, it suggests something odd is happening \u2014 because 7.6.4 should support `var` just fine.\n\nHere are possible causes for the error, and steps to fix or diagnose it.\n\n---\n\n## \u26a0 Possible Causes\n\n1. **Script being run under Windows PowerShell (v5.1), not PowerShell 7.6.4**  \n   Even if you *have* 7.6.4 installed, you might accidentally be using an older version.\n\n2. **The `pwsh` path alias or shell launching isn\u2019t going to the newer version**  \n   Maybe a shortcut, task, or script launch is still pointing to the older Windows version.\n\n3. **Policy, module manifest, or environment-specific blocks or wrappers**  \n   Something might be overriding script handling, loading the script in a restrictive compatibility mode, or using a host that doesn\u2019t support newer syntax. For instance: some PowerShell hosts (e.g. certain ISE versions or embedded hosts) limit language features.\n\n4. **Execution policy or system security settings**  \n   If strict execution policy or system constraints aren\u2019t met, the script may fail early or partially, causing misleading error messages.\n\n---\n\n## \u2705 What You Should Check / Try\n\n### A. Confirm you are really in PowerShell **7.6.4**\n\nRun these in your terminal:\n\n```powershell\n$PSVersionTable.PSVersion\n$Host.Name\n```\n\n- `Major` should be **7**, `Minor` **6**, `Patch` at least **4**.\n- `Host.Name` should show something like `PowerShell` (core) not `Windows PowerShell` or `ConsoleHost` in legacy mode.\n\nIf it shows something older (like 5.1), you\u2019re not running the correct version. Make sure you're launching `pwsh.exe` (the core version), not `powershell.exe`.\n\n### B. Run the install script explicitly via `pwsh`\n\n```powershell\npwsh -ExecutionPolicy Bypass -NoProfile -Command \"& { $(Invoke-RestMethod 'https://aka.ms/installaishell.ps1') }\"\n```\n\n- This forces use of PowerShell Core\n- The `-NoProfile` avoids loading potentially conflicting legacy profiles or modules\n- `-ExecutionPolicy Bypass` helps with any restrictions\n\n### C. Inspect the script content around where the error is\n\n- If possible, download the script locally:\n  \n  ```powershell\n  Invoke-RestMethod 'https://aka.ms/installaishell.ps1' -OutFile installaishell.ps1\n  ```\n\n- Search for `var` usage to see context. If `var` is being used in a way that might be rejected (for example, inside a configuration manifest), that could reveal more.\n\n### D. Check for module version and PSReadLine\n\n- Ensure PSReadLine version is at least `2.4.2-beta2` (AI Shell prerequisite) ([s.itho.me](https://s.itho.me/ccms_slides/2025/10/21/69dd6640-86fd-4c78-9473-4f2b034a5c4c.pdf?utm_source=openai)).\n- Sometimes older modules like PSReadLine can interfere if your profile or default shell loads them early.\n\n### E. Consider relative compatibility\n\n- If something in your environment is forcing scripts to be parsed as the older `Windows PowerShell` (v5) mode (e.g. profile settings, `PowerShellHostVersion` in a module manifest, or forced host), that would throw errors for unsupported keywords like `var`. \n\n---\n\nIf you want, I can help you run a diagnostic snippet (small script) that detects *exactly* whether you're in the correct host/environment, spot where `var` is coming from, and help patch or work around it. Do you want that?"
