Error: Ddraw.dll when Microstudio is opened

[clyde]

I have the MTU microstudio - I cannot open the icon microstudio. The message I get when trying to open this icon is as follows:

"The microstudio.exe file is linked to missing export DDRAW.DILL:Direct DrawCreate.ex."

"C:\ProgramFiles\Micro Technology Unlimited\Microstudio\MicroStudio.exe. A device attached to the system is not functioning."

Can someone help me by explaining what a DDRAW is and how I can correct the problem?

Thanks, Clyde.
