Error: This operation is not supported with BTT enabled

I haven’t seen this error before.  A Chilkat user reported it, and then quickly found the answer:

When trying to Create the Chilkat_9_5_0.http object with this example: 
https://www.example-code.com/vbscript/curl_username_password.asp 
, there's a message that the ActiveX Component can't create it, because 
"System:  This operation is not supported with BTT enabled." 

The cause of the problem had to do with a 32-bit/64-bit mixup.

"I installed the 32-bit Chilkat ActiveX, but was using VBScript from a 64-bit IDE. When I ran the 32-bit version of VBSEdit, it worked fine. "
