Did you:

1. verify that your system satisfies all the Requirements to run DynamIP?
2. get the latest version of DynamIP (you can always find the latest version at http://www.bigfoot.com/~DynamIP/)?
3. run RegClean (Freeware from Microsoft) to clean up your registry?

This section describes some common setup problems and their solutions. If you can't even install or launch DynamIP then you got ahead of yourself - check the section Installation Problems first.

If DynamIP crashes with a "System Error" or an "Unspecified error" whenever you try to select one of the Setup menus (e.g. Setup|Options) then you should read these MSKB articles.

If you encountered and solved a problem not mentioned here please drop me a line so that I can add your solution to the above list. Thanks.
