    TestComplete installs it's own python instance so the third-party package in the site-packages folder won't work. If you copy the third-party package you want from the site-packages into the TestComplete python folder it will work.

     

    For example I use the pytz and tzlocal packages. After installing through pip, I copied those folders from the site-packages folder into C:\Program Files\SmartBear\TestComplete 11\Bin\Extensions\Python\Python34\Lib . Then just import like regular and it should work.

     

     

    I think you could also add the site-packages folder to the sys path like you are in your code, I think the mistake you are making is not escaping the backslash character in your string or using a raw string. So it should be sys.path.append("C:\\Data\\Python\\Lib\\site-packages") or sys.path.append(r"C:\Data\Python\Lib\site-packages")

    import win32com.client as win32

      Did you copy your entire site-packages folder or just the win32com folder? You don't want the whole site-packages folder, only the folder of the third party package should go in the Lib folder, i.e. only copy the win32com folder into Lib, not entire site-packages.

        Thanks, i copied the win32com folder to Lib only now. but another error pops when i run the script

         

        ImportError No module named 'win32api'

        Error location: Unit: "HorizonTestSuite\HorizonAutoTest\Script\genfuncs"

        Line: 7 Column: 1.

         
         
        It is weird since i didn't use win32api, my script only import win32com.client
         
        import win32com.client as win3
