This is due to the changing to a 64-bit platform. You are now launching with the 64-bit script engine. Unfortunately, the QC API is 32-bit only and cannot use
the 64-bit engine.

There is a legacy 32-bit script engine located at:


You can launch your script via command line by browsing to the 32-bit script engine
above and passing the path and script as an argument.

example:  C:WindowsSysWOW64> wscript.exe c:myscript.vbs

Alternately, you can change your default script engine as follows:

1) Open the registry editor and locate to the following path:


2) Change the value of the (Default) key:

**For 64-bit script engine:**

''%SystemRoot%System32WScript.exe'' ''%1'' %*

**For 32-bit script engine:**

''%SystemRoot%SysWOW64WScript.exe'' ''%1'' %*
