I am trying to go from 32 bit Vista to 64 bit Windows 7.

The 32 bit Vista was installed by mistake. My system can handle a 64 bit OS. Now I have finally found the time to upgrade. But the 64 bit intallation DVD can't be read from my OS. Any Advice?

Do I need to boot from that DVD drive? Will that work?

Download and Install Windows Easy Transfer for Windows 7 on Vista. Save data to an external drive with it. Install Windows 7 x64 and use easy transfer (built into a windows 7) to load your data back on. Reinstall all of your programs.

Are you sure your laptop or computer is 64bit compatible? Use a 64bit checker to make sure ... otherwise you won't be able to install 64bit OS on it if it is not compatible. So you will use Windows 7 32bit instead.

If it is compatible, then do a clean install as others have said. Not upgrade.

Externally back-up all your data. Then do a fresh clean format / install.

Or install to a different partition/drive (different drive by preference).

Yes - you CAN do a clean install from upgrade media (this has been possible since 9x/NT); all that is required is that a qualifying product be accessible during the installation (first stage or second stage - for NT-based Windows, it's the second stage).

Also, you can import (via Files and Settings Transfer) from x32 to x64 - I have, in fact, done so.

Still, a clean install *is* preferable (of the old applications, if you want to still use them).

Suggestion/tip - if an x64 version of an application is available, use that instead (unless constrained by plug-ins or add-ons for the application in question); I crossgraded from Firefox to Waterfox and (thanks to having already installed the x64 versions of my plug-ins), I basically hit the ground running. NOTE - GreaseMonkey (and scripts developed for it) *are* compatible with Waterfox.

      That is $130 more than I paid for my 4TB a year ago. How is this a deal?
    • JetBrains' new AI-first 'IDE' JetBrains Air is now on Windows

      By David Uzondu · Posted

      JetBrains' new AI-first 'IDE' JetBrains Air is now on Windows by David Uzondu JetBrains has announced that JetBrains Air, its Agentic Development Environment (ADE) is now available for download on Windows x64 and ARM. You might not be familiar with JetBrains Air. It's this new desktop app that the company launched back in March 2026 to let developers hand off tasks to AI agents instead of writing every line manually. You can see it as more of an Agentic Development Environment (ADE) rather than a traditional Integrated Development Environment (IDE). The latter builds its features around a central text editor, while the former arranges everything around the AI agent itself. Here's how JetBrains describes it: Air was born from the ashes of Fleet, an experimental editor that the company quietly killed in December 2025 after realizing that competing directly with VS Code was a losing battle. The company repurposed Fleet's lightweight, modern architecture to build Air, transforming a basic code editor into a workspace for running multiple AI agents. When Air launched, it was only available for macOS. It wasn't until earlier this month that Linux users got a chance to play with the software. Now that Air is on Windows, you can do things like map out a complex feature in Plan mode and watch an AI write the implementation plan to a markdown file before writing any code. You can iterate on this plan, add references to specific classes or files, and choose whether to run the agent locally or inside an isolated Git worktree. Running agents in parallel means you can have Claude refactor a database schema in one branch while Codex writes tests in another, leaving you free to do other important things. You can even set up a pipeline where Claude writes the code, and Codex reviews it. At the moment, Air is free. If you have a JetBrains AI Pro or Ultimate subscription, you get full access to the built-in agents, though there's also the option to Bring Your Own Key (BYOK) to run APIs from Anthropic, OpenAI, or Google. If you're interested, here are the download links for both x64 and ARM64.

      Depending how you’re wiring it internally, but try to put it inside conduit, that way in the future you can more easily replace cables, compared to running inside studs alone At least cat6a too

      I bet Meta has lots of info on you anyway, gathered by other means. And Google, and Microsoft, and every other tech giant. If you use some form of modern electronic device, they own you already...
