This is indicating that the 3rd party lib that you are using cannot be started because:

1. It isn't resigered / installed on your system.
2. Some other component the third party lib uses is not installed.

There are a whole raft of app that will help you find what dependencies the lib requires...

Take a look here for some useful utils...


'listdlls' and 'procexp' may be useful...

so kindly follow the steps below

first off I don't know what the executable name is of your library so you'll have to fill that bit in yourself...

1. Open a cmmand window
2. Go to the directory where the library exe is.
3. Run regsvr32.exe e.g. regsvr32 /i

this will pop up a messagebox indicating whether this has succeeded or not.. If it hasn't succeeded then I suggest you going back to the vendor of the library and get proper installation instructions...

Do a google search for regsvr32....


Thanks & Regards,

Mark if the answer is true
