failed loading mesa.dll

[acarapelle]

I'm using compenentswork Active X in delphi. I'mtrying to use a TCWGraph and delphi says "failed loading mesa.dll". Everything was working fine before (I was using NI-DAQ 6.7 and compenents work) but now it doesn't work anymore since I installed NI-DAQ 6.9.2. I've uninstal everything (Delphi, compenentworks and NIDAQ) and re-install everything and it still doesn't work

I believe that this is happening because mesa.dll did not get installed with NI-DAQ. Mesa.dll should be installed if you have installed LabVIEW, the LabVIEW runtime, or Measurement Studio. If you have not installed any of these products, you can copy mesa.dll to your Windows sytem directory and that should resolve the issue.

If you do not have any of the products listed above and you can't get mesa.dll, you can resolve this issue by changing the graph's GraphFrameStyle property from cwGraphFrame3D to cwGraphFrameClassic. This should make the graph work the way that it did before.

I have re-instal labview 5.1 and it didn't solve the problem. There is no mesa.dll installed by labview 5.1.
Besides, when I use programs that I made before with compenents works active X the windows now says "Evaluation copy" but it is not the eveluation copy, I purchased compenents works. All I want is to use the Active X in delphi like I did before. Please help !
