What steps will reproduce the bug?

Installing Bionano Access, that requires Windows 10 and Node v12.22.10,
The stderr says

Folders: 404
Files: 3483
Size:       5745411300
Compressed: 534396129
Postgres psql (PostgreSQL) 17.3 found...
v12.22.10
6.14.16
Installed Node v12.22.10 found...
Installed Node 6.14.16 found...
NPM version not compatible! Please install NPM v8.10.0 or higher
Cleaning up...

How often does it reproduce? Is there a required condition?

every time

What is the expected behavior? Why is that the expected behavior?

I guess the fact that Bionano software finds the 6.14.16 version makes it fail the installation

What do you see instead?

can't complete installation

Additional information

The software I am trying to install is Bionano Access for Windows, v1.8.2 here https://bionano.com/software-downloads/

You should update your Node.js version since v12 has been EOL for a long time. The application is expecting a never npm version.
Closing since this issue is not related to Node.js but to bionano

Hi Marco,
Sorry to reopen this, but the Bionano software explicitly asks for that specific node version, so I don't have the choice of using a newer version.
more in general, why do I find that 6.14 version appearing once I install the 12.22?
Thanks,
Dario

Hi Dario,
The 6.14 is the npm version.
If you cannot update Node.us then you have to upgrade your npm version separately npm install -g npm@8.10.0.
This issue has nothing to do with Node.js itself but with bionano, so for the future issue please reach out to bionano.

Permissions: Ensure you run the Command Prompt or installer as an Administrator, especially on Windows 10, to avoid "Access denied" errors (as seen in some web reports for Node.js installations on Windows 10).
Antivirus/Firewall: Some users reported antivirus software (e.g., Avast, AVG) interfering with Node.js or NPM installations on Windows 10. Temporarily disable your antivirus during installation if issues persist.
NVM for Windows: If you prefer using NVM, ensure you install only Node.js v12.22.10 via NVM (nvm install 12.22.10) and update NPM (nvm use 12.22.10 followed by npm install -g npm@8.10.0). However, the web results suggest NVM for Windows can sometimes cause installation issues (e.g., "Access is denied" or download failures), so a direct installation might be more reliable for this case.
Postgres Detection: The installer mentions detecting PostgreSQL 17.3, which is fine as long as it doesn’t conflict with Bionano Access requirements. Ensure PostgreSQL is installed and running correctly, but this shouldn’t affect the Node.js/NPM issue.
