Node.js v22.19.0

I've trying to open link (from previous result) manually and after sign in and choosing organization i've see the next result: 

When "Contacting the Adobe CLI..." is complete - next text is appears 

By clicking the link i've seen the next text:

Error described above appears in "cmd (command prompt)" and "PowerShell"

sometimes "aio login" can be executed without any problems (default browser automatically opens and after sign in i can use aio)

Hi @DmitriyDe 

Option 1: Check Environment Variables

1. Open Command Prompt.

2. Run:

   echo %SystemRoot%

   You should see something like:

   C:\Windows

   If it’s empty, that’s the issue.

3. Fix it manually:

   • Press Windows + R → sysdm.cpl → Advanced → Environment Variables

   • Under System variables, click New (if not exist) and add:

     Variable name: SystemRoot Variable value: C:\Windows

   • Also check ComSpec—it should be:

     C:\Windows\System32\cmd.exe

4. Restart your terminal and try:

   aio login

---

Option 2: Set PowerShell Path Manually

If your PowerShell path isn’t resolving, set it before running the command:

setx PATH "%PATH%;C:\Windows\System32\WindowsPowerShell\v1.0"

Then restart the command prompt and run:

aio login

---

Option 3: Force Browser Launch

Sometimes the CLI fails to open a browser automatically. You can use:

aio login --no-launch

This prints the URL to the terminal—just copy-paste it into your browser manually.

After successful login, it should say:

✔ Successfully logged in

---

Option 4: Reinstall Adobe I/O CLI

If the issue persists:

npm uninstall -g @adobe/aio-cli npm install -g @adobe/aio-cli

---

Option 5: Node.js Path Issue

Sometimes Node itself doesn’t resolve PowerShell correctly.
Ensure you’re using a stable version (LTS preferred):

node -v

If you’re on v22.x (as shown in your log), downgrade to v20.x LTS—Adobe CLI has better stability there.

Hi, Syed! Thanks for the answer, but unfortunately nothing helped.

.

I should clarify. Sometimes I can perform aio login, but I don't know what's causing it.

It seems like sometimes when I run the aio login command, an error occurs because aio thinks I'm already logged in, causing some sort of conflict.

Simply waiting has helped me many times. A couple of days later, when I returned to this problem, it simply disappeared and I was able to log in without any problems.

PS: aio logout doesn't help.

Hi @DmitriyDe ,

The error appears because aio cannot find PowerShell on your system, so it cannot open the browser automatically. Your PATH is missing the default PowerShell location, and Adobe CLI fails with the “spawn ENOENT” message.

follow below steps,

1. Add PowerShell to your PATH
   Add this path in Environment Variables > System > Path:

C:\Windows\System32\WindowsPowerShell\v1.0\

2. Restart CMD/PowerShell

3. Run again:

aio login

After this, the login will work normally because the CLI can open PowerShell and launch the browser.

In short: Fix your PATH so PowerShell is accessible > aio login will stop failing.

Thanks,
