Re: my object names hase changed to HwndWrapper Hi, I come across the same problem. Do you have the answer now? ImportError:DLL load faild: %1 is not a valid Wind32 application Hi, I'm trying to import a third party library in Python script in TestComplete. TestComplete keeps reporting "ImportError:DLL load faild: %1 is not a valid Wind32 application". (see error1 attached) However, if I use python.exe to import this library, it looks fine (see success2 attached). Can anyone give me some suggestions here? Solved
