I've created a bit of a mess for myself. Over the last few days I have had to do a few system restores due to accidentally changing my user account to an administrator account on Windows. Long story short, it looks like I finally have everything settled, but when I tried to open Minecraft today I got this error:

Please fix the error and restart.



I assumed the best thing to do would be to uninstall minecraft, but I don't see it on my uninstall list. Can anyone help me out with this?

You don't need to uninstall minecraft, you need to fix the permissions on your user profile so that you have access to it again.

Go to C:\Users and give yourself full control of Krystalyn, I suspect that it is now owned by Adminstrator or something similar.

When I do that it gives me the error "you must provide administrator permission to change these attributes" I'm pretty sure that's how I got into this mess a couple of days ago. I think that when I clicked okay it changed my user account to an administrator account and half of my stuff disappeared into the aether. I just recovered it this morning and am reluctant to risk losing it again.

update: I went to c:\users and opened up the properties for Krystalyn, noticed it was marked as read only, so I changed that (which required administrator permission.) I'm still receiving the same error. When I look at the security properties for that user I see everything checked as "allow" except for "special permissions." When I check out the account type in the control panel, Krystalyn is an administrator account. I feel like I must be missing something or misunderstanding where I'm supposed to be making the changes.

Only you know what you did exactly that you then spent time undoing. If the permissions are okay on the Krystalyn directory, then what about each folder down from there to "AppData\Roaming\.minecraft\launcher.jar" somewhere there could be a permission problem... if not then I'm not sure what else could cause an access denied error, unless perhaps its your antivirus blocking access to the file while it is being scanned. But that would be a coincidence if it occurred right after your account issues.

Thanks Gerbil, what I've found is that when I change the folders from "read only" it just changes back, so I'm working with another "how to" to fix that problem... ugh

as it turned out, deleting all of my minecraft files and starting fresh was the way to go.
