I am assuming that you have checked that tkds30xx_32.dll is actually on your system...and if so, I have attached an application called depends.exe
This looks at a DLL and shows you what modules (external DLL's etc) are required for that module. It may have a dependancy that is missing.
More simpler, it may be that the DLL is not in a path that the calling application is expecting. A quick check for this would be to place the offending DLL in a folder specified as an existing path, or by appending the current folder in your system path.
Hope this helps,
Chris
