Sometimes when troubleshooting a Google support case that involves the Chrome browser crashing/not responding, you may be asked to provide the version number of Chrome before your most recent update. Documentation on how to get this is not very public, so here are the steps to take to get this information.
- This was only tested on Windows 10 devices
1. Navigate to Chrome's install location
This may be located in one of two spots depending on how up-to-date Chrome is:
C:\Program Files (x86)\Google\Chrome
- (ensure you have 'show hidden items' enabled)
2. Locate the 'Temp' folder
Inside the Chrome installation directory will have a folder named 'Temp'. Open this and keep navigating down until you find "old_chrome.exe". This is the old installation of Chrome before you updated.
3. View Properties of old_chrome.exe
Now just right-click on the executable and then go to 'Properties'. After this click on the 'Details' tab which is where you'll find the version of this .exe. This is the previous install of Chrome on your device prior to your most recent update.
