This post is mainly valid if you do NOT own a LEADTOOLS multimedia toolkit.

The evaluation nag message is being caused by a DirectShow filter left on your machine. If you do not wish to purchase it and just want to remove it from your machine, please see the attached PDF file for detailed removal instructions.

If you follow the instructions in the PDF file and still face problems related to LEAD filters, please email support@leadtools.com with full details of the problem and what you tried to solve it.

Please follow these instructions to accommodate more recent versions of Windows with UAC.

The evaluation message you are getting is coming from one of our DirectShow filters or codecs which can be used by ANY application that implements DirectShow. Most likely, it was left on your computer by another software vendor other than LEAD since we supply these as tools for other software developers to use. To get rid of this nag message, you must follow these steps:

First, download the SysEnum utility from the LEADTOOLS fileshare service.

When prompted, use the password "LEADTOOLSsysenum" -- as cased, without the quote marks. This will download the SysEnum utility to your browser's default download folder.

Run the SysEnum utility.

When you select a Device class in the list on the left, the DirectShow filters on your machine in that category will show up in the list on the right. Most likely, any LEAD filters will show up under Audio Compressors, DirectShow Filters, Video Capture Devices, or Video Compressors.


To unregister the DLL, open the Start Menu. Scroll to Windows System and find "Command Prompt". Right-click "Command Prompt". This will open a context menu. Hover over "More" to open a submenu, then select "Run as Administrator".

Depending on your system settings, this will open the User Account Control (UAC) confirmation dialogue. Select "Yes". A window will appear with "Administrator: Command Prompt" in the title bar. From here, regsvr can be used to unregister the DLL. Enter "regsvr32 -u [DLL]" (without the quotes) where [DLL] is the full file name you found earlier.


Press "Enter" to unregister the library. Note it'll be necessary to repeat these steps for each library you wish to remove. The Command Prompt window can be closed out after this task is complete.

After you have unregistered the DLL, the DirectShow framework on your machine will not be able to find it, therefore it is not necessary to remove the file to get rid of the nag message, but it is recommended since you are not going to use it. Browse to the directory where the DLL is located using Windows Explorer. Right-click on that file and select “Delete”.

If you follow these instructions and still face problems related to LEAD filters, please email support@leadtools.com with full details of the problem and what you tried to solve it.
