automation support dll

[Vector]

Hi

I am adding 3rd party DLL in my program using ActiveX controller option. In some computer my exe file is working properly and in some computer it is giving me error. I checked that in debug mode and I found that it is saying like " Function CA_CstrintoSTR (return value -214722059) could not load Automation support DLL" and becasue of that I am not able to use DLL's call. I also register that dll with regsvr32. But same DLL is working on other computer with same enviorment. Can you please help me is there any patch is missing or some runtime engine problem.

Thanks in advance

The LabWindows/CVI Runtime should install the file "cviauto.dll" into the Windows\System32 directory. If this file is not there, TestStand and other applications and DLLs that use CVI's ActiveX Automation Library will not work. See if this file exists.
