Converting Microsoft Office 2007 from Trial to Full Version

This post provides information to convert Microsoft Office 2007 from trial to full version without product key. This post is not intended to be used. Drop comments / opinions.

This requires that Microsoft Office 2007 has been installed without the product key in the first place.

Once Microsoft Office 2007 has been installed with no product key, proceed as follows:
1. In Windows Explorer, browse to the following folder:

C:\Program Files\Common Files\Microsoft Shared\OFFICE12\Office Setup\ Controller\Proof.en

2. Right click on Proof.XML file, select Open With in the right click menu.

3. In the Open With window, select Notepad to be used to open the XML file.
[Note: In Windows Vista, if you can’t see the Notepad option, simply double click the “Other Programs” to unhide it.]

4. Scroll down to the bottom of the Proof.XML to locate the following lines:

<feature Id="SetupXmlFiles" Cost="1248″><optionref Id=”AlwaysInstalled”/></feature>

5. Change the AlwaysInsalled to neverInstalled so that the line looks like following:

<optionref Id="neverInstalled"/> 

6. Save the Proof.xml file.

[In Windows Vista, you may need to take ownership and grant full access permission to yourself before able to modify the file. We already have a detailed article on that.The detail steps on How to take Ownership of a File in Windows Vista or Windows 7 is listed below this instruction]

7. You can now launch Microsoft Office 2007 application such as Word, Excel, Powerpoint, Outlook and etc without prompting for activation.

How to take Ownership of a File in Windows Vista

Step 1: First access the command prompt

Click the on the start button>All Programs>Accessories

Step 2: Right Click on the command prompt

Step 3: Select Run as administrator.

Step 4: When the Alert Dialog appears, click Continue.

Once you have your elevated command prompt, follow these steps:

For our example,

At the command prompt, input takeown /f filepath.

C:\>takeown /f "C:\Program Files\Common Files\microsoft shared\OFFICE12\Office Setup Controller\Proof.en\Proof.xml"

Now, press Enter on the keyboard.

You will get a message displaying that this completed successfully.

Step 5: Now input icacls filepath /grant yourusername:f.

C:\>icacls "C:\Program Files\Common Files\microsoft shared\OFFICE12\Office Setup Controller\Proof.en\Proof.xml" /grant Username:f

Step 6: A message will be displayed that this completed successfully.

You are done, now you can modify or replace the file. When you are done, simply remove the permissions to keep the file secure.

    I get a response in windows 7 saying that

    Username: No mapping between account names and security IDs was done.
    Successfully processed 0 files; Failed processing 1 files.
    It then gives me the command prompt again.
