I'm trying to open a php file type but its saying it doesn't know what program to use, I select word pad and tick the remember program box and when I try to open it again it asks me repeats what I just said, also I cannot create .php file types but 2 days ago I could.When I goto the registry I try to open the .php key and it says"Cannot open .php: Error while opening key" Does anyone know a way of fixing this?

Delete the php key in the registry and try associating the extension again.

I got this error:-"Cannot delete .php: error while deleting key"

[quote name='webmonster']I got this error:-> > > > "Cannot delete .php: error while deleting key"Are you logged on as an administrator user? I would think that non-admins aren't allowed to do that stuff.

[webmonster]

I'm logged in as admin.

Definitely logged in as admin. If you are not an admin, you can't even access the registry!Open a My Computer windows. Click View, folder options, file types.Scoll down to the php row. Select php, click delete.Try associating again.

Tried that and it doesn't delete, and I'm sure that I'm logged in as admin because theres only one account.

Click the Change button and try to change the program.

Tried it did nothing and I forgot to say this problem only started after I uninstalled this:-http://www.alienware.com/StandalonePages/invaderdownload_pop.aspx

What is that program? I went to the link and it asked for a email address. I am reluctant to give it out.

[webmonster]

Changes the theme of your computer and you can put a fake email.

According to http://filext.com/de...p&Search=Search php files do not seem related to this alienware theme program.If you believe this program caused the problem, you can try installing and uninstalling again to see if it solves the program.

Just tried and it didn't do anything.

I had a very similar problem, if not the same on 392 registry keys. I only noticed it when I lost the ability to view .pdf files. To fix the problem you need to open Registry Editor, find the troublesome registry key(s), go to permissions, add the group Everyone (just to be safe), give full control, click on the advanced button, and go to the owner tab click on a name and check the "Replace owner on subcontainers and objects" box. Then click OK. it should give you a message like "Unable to set new owner on .php Access is denied." Click on ok again to close the permissions box, and you should have access to .php registry key once again. That solved the problem for me (well the 40 or so that I've fixed so far).
