1. Look for the file normal.dll on your system.
2. If you find it, open a command prompt (Win-Key + R and enter CMD) and navigate to the folder where it is located. If you didn't find the file stop here.
3. Enter the following into the command prompt "regsvr32 normal.dll"
4. If the message box says that the registration was successful try to run your application again. If the application does not run correctly make sure you unregister the dll file by entering the following into the command prompt "regsvr32 /u normal.dll". If the message box says the dll file was not registered because there was no entry point then this isn't going to work.
