As you may know, there are a number of Early Access Release Channels for Google Chrome the let you test out new features that are still under development. For example, you could be using Google Chrome 9 right now, if you were so inclined and were prepared to put up with a few errors and instabilities now and then. But what happens more often than not when a user switches to a beta channel or dev channel of Chrome is that they switch back to the stable channel after too many crashes. This is all well and good—it’s just a matter of reinstalling Chrome—but when you move from a newer version of Google Chrome to a previous version, you’ll get this error message upon launch:
Your profile can not be used because it is from a newer version of Google Chrome. Some features may be unavailable. Please specify a different profile directory or use a newer version of Chrome.
So, Chrome lays out the problem, and even the solution, but how the heck do you specify a different profile directory in Chrome? Search me. Personally, I think the easiest way to fix this is to just delete your profile and start from scratch. You won’t lose anything like saved form data, passwords or synced bookmarks, but it will get rid of this pesky error message telling you that your profile cannot be used. Here’s a quick fix:
Step One
Launch Windows Explorer. Navigate to C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\User Data\Default
Don’t forget to sub out your Windows user name for YOURUSERNAME.
Note you may need to Show hidden files and folders to get here. Click Start and type Folder Options in the search bar and choose Folder Options. In the View tab, select Show hidden, files folder and drives under Hidden files and folders.
Step Two
Locate the file called web data. Delete it.
Note: If you’re nervous about doing this, you can simply rename it to “web data.bk” to save it as a backup. But deleting this shouldn’t have any adverse effects.
Step Three
Launch Google Chrome. The error message is gone!
That’s all there is to it. What a pesky error—luckily, it’s an easy fix.

Thank you very much, this is just what I needed! I wish they had anticipated this (probably common) downgrade cycle.
Thank you so much. Wish I had checked here earlier, would have saved myself some time. Again, thank you so much.
Can you please give instructions for the mac.
I need mac instructions too.
Go to your user home folder -> Library -> application support -> Google -> Chrome -> default -> delete the web data file. Hope that helps
Thanks, works 100%
Thank you very much! It worked like a charm.
thanks you … you saved my day
thanks you … you saved my day
Thanks, this worked great
For anyone else on a Mac, the file to nuke is in
~/Library/Application Support/Google/Chrome/Web Data
Thank you very much, it worked!
wouldn’t this delete all of the bookmarked pages in my Firefox?
i cannot find C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\User Data\Default in window 7 plszz help
C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\User Data\Default
should be
C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\Default
That’s odd. I dbl-checked in the 32-bit and 64-bit ver and it’s C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\User Data\Default for me on both.
Ok. Try using explorer to search for file “web data” in your USER folder “My Documents” (or whatever the f*** it is on Windows 7). Then delete it.
I have no “Web Date” file!!
Thta’s because it’s “web data” <– check speeelling

cant find app data in my user?
This fix causes another problem.
Can’t see history items anymore. The history tab is blank now. I sensed it before I tried the recommended fix, but knew no other way to fix the error message (which was more annoying).
Any fix for this issue, or did this happen only on my PC?
PS: OS = Windows 7

I had a major issue with Microsoft Office and then the “tech” from Microsoft deleted an important file that completely screwed up my entire computer. After I thought I had everything fixed, Google kept popping up with this message. Your blog was the ONLY one that gave an easy fix that didn’t require any major editing in the cache. Thank you!! I wish I could hug you, haha.
