Error 20540 while changing Appl. from VB5.0 to VB 6.0


I am getting run-time error 20540, 'Missing or out-of-date export dll' for my Application, after i changed the VB version from 5.0 to 6.0


Does anybody has the solution to this?

Thanks in advance.



  • You can go to and find the Visual studio page, there you'll see bugs description if you don't find yours then you can write them about your bug in details and send them this.

  • Hi,

    I'm not getting the error any more. Here's the solution which i had received from some other help site.

    Solution: Search for U2F*.DLL and copy them in the

    windowssystem directory.

    Thanks for ur help.
