ActiveX component can't create object - TDApiOle80.TDConnection

Some times we get error as "Windows7 64 bit - ActiveX component can't create object TDApiOle80.TDConnection" while running Quality Center related VBScript files on WIndows 7, 64Bit machine...




If you are on 64bit machine, by default QC OTA API script will run with the 64 bit version of wscript.exe.
But QC is a 32 bit app, so you need to run it from a 32 bit version of wscript.exe which is located at c:\Windows\SysWOW64\wscript.exe.

You can run the .vbs file from the start -> run as-
c:\Windows\SysWOW64\wscript.exe "path of QC script file\.vbs"
