Authorization code does not work--and the number changes

[jarvis24]

Your probably do not have read/write permissions for the MediaLab/DirectRT folders. This will cause the license check to fail. if this is the case then the folder permissions need to be set by someone with administrator-level access. The following steps should make everything work (e.g., while logged on as a regular user):

1. Log on as an administrator
2. Right click on the MediaLab/DirectRT folder and select Properties and then Security and ensure that regular users have Read/Write permission.
3. Only if you do not see a Security tab, then:
4. Open Folder Options in the Windows Control Panel. On the View tab, make sure Use simple file sharing is not checked. It should be one of the last options.
5. Go back to step #2.

That should do it. Let us know if you have any trouble with it.

Newell Edit (DirectRT 2008 [Vista-compatible version] / 2010):
To assign the proper permissions to a 2008/2010 copy of DirectRT, the following steps will need to be taken:

1. Log on as an administrator.
2. Open up Windows Explorer. This can be accomplished through the start menu or by pressing the 'Windows key + E' .
3. Navigate to the folder Program Files\Empirisoft\DirectRT 2010 .
4. Right-click on the folder titled Components and navigate to the Properties menu item.
5. Navigate to the Security tab. If you do not see the Security tab, Blair's comments above note how to enable the tab.
6. From the security tab, select the button 'Edit...'
7. In the top control that lists each user group, select Users. In the bottom control select the checkbox for 'Full control' under the Allow column. Upon seeing that each checkbox is now filled for this column, select Apply and then press OK .
8. Press OK on the previous dialog box. You're now finished setting up the proper user permissions.
