I have Chrome Portable 4.1.249.1036 (41514).  I'm having trouble with extensions crashing.  One of the extension vendors suggested upgrading to a newer version.  Google has 5.0.375.55 at chrome.google.com, so here's how I (tried to) upgrade.

Chrome 4 is installed in S:\Chrome-Portable.  I'm going to (try to) put Chrome 5 in S:\Chrome-Portable-5.

  1. Install from chrome.google.com.  Google installed itself to C:\Documents and Settings\username\Local Settings\Application Data\Google\Chrome\Application.
  2. Copy S:\Chrome-Portable to S:\Chrome-Portable-5
  3. Rename S:\Chrome-Portable to S:\Chrome-Portable-4 (just in case some of the files I copied refer to S:\Chrome-Portable).
  4. Start Chrome Portable from S:\Chrome-Portable-5, just to be sure it works before I start messing with it.
  5. Copy the contents of C:\Documents and Settings\username\Local Settings\Application Data\Google\Chrome\Application to S:\Chrome-Portable-5\App\Chrome-bin.
  6. Delete S:\Chrome-Portable-5\App\Chrome-bin\4.1.249.1036.
  7. Run S:\Chrome-Portable-5\GoogleChromePortable.exe, and check the version.  It reports 5.0.375.55.
  8. Uninstall the installed Chrome via Control Panel.  (The uninstall in the Google Chrome folder of the Start menu failed to find setup.exe.)  Choose "Also delete my browsing data."
  9. Run S:\Chrome-Portable-5\GoogleChromePortable.exe, and check the version.  It reports 5.0.375.55.
  10. Spot check some extensions.  They work.
  11. Call it a success.
