During installation of Philips SpeechExec Pro software on a Vista machine, I recieve a Windows Installer Error 2738

Error 2738 may occur in Windows Vista when a custom install action is required by the SpeechExec software installation and VBScript is not registered.

Try this..

• Start Button > All Programs > Accessories
• Right-click onCommand Prompt”
• SelectRun as Administrator”
• Type cd and press ENTER
• Type cd  C:WindowsSystem32 and press ENTER
• Type regsvr32  vbscript.dll and press ENTER

You should receive a message that the DLL has been successfully registered.

Try the SpeechExec installation again !
