Authorization code does not work--and the number changes

Also.. if you install an update file such as medialab.exe, be sure you read the readme.txt file that comes with it. The update file must go into the existing MediaLab folder, overwriting the older version of the same file. If you simply try to run the update file from some other location, you will be prompted for a new code.

Three other tricks:

For Windows XP, 2000, etc:

Click on the DirectRT / MediaLab folder (the entire folder) and instead of read / write, select 'full control'.

Also, if the code still doesn't remain stable after making these changes, delete the file 'license.dll' from the MediaLab / DirectRT folder. Restart the program, then see if the new number generated remains the same.

I have known of one user who found that made a difference.

For Windows Vista and the Beta version of DirectRT:

When logged in as an admin, try deleting the file license2008.dll and then start the program again. The file will be re-generated. See if that gives you a stable code when you open and close the window a few times.


Once the code is stable, we can send you an activation code which works.

One final idea which especially relates to site licenses and IP-based authentication:

On rare occasions, people have experienced a message box displaying

"Automation error ClassFactory cannot supply requesed class"

A solution to this is typing the following from within the windows 'Run' menu:

regsvr32 c:\directrt\license2008ip.dll

One user also reported that re-installing solved the problem when the 'regsvr' command mentioned above didn't work.

Important Note:

Blair's post at the top of this thread refers to changing the read/write permissions of the actual folder that DirectRT / MediaLab live in. This is typically C:\MediaLab or C:\DirectRT for the 2008 versions.

If you just right-click on the MediaLab / DirectRT icon on your desktop, then it will change the permissions only on the shortcut--not on the main folders and so changes won't have the desired impact.

So the important note again here: Be sure to use the file explorer / My Computer shortcut and apply these changes to the program folder.

It worked! The group 'USERS' did not have write permission regardless of whether the user had admin privileges. I added the write permission and relaunched DirectRT and it gave me the original code. I entered the response code you sent and it worked! Thanks and have a good weekend.
