RobotFramework - AutoItLibrary: Importing test library “AutoItLibrary” failed

问题:

Can anyone support me this case?

I install the same steps in 2 machines with similar configurations. But one machine works. One machine fails when importing AutoItLibrary.

View Ride log - the error shows:

I had the same problem and tested with 32 bit library then worked.

@echo off setlocal  set "jsfile=%temp%\autoit3x_comtest.js"  (     echo try {     echo     oAutoIt = new ActiveXObject("AutoItX3.Control"^);     echo }     echo catch (e^) {     echo     WScript.Echo("Catch: " + e^);     echo     WScript.Quit (1^);     echo } ) > "%jsfile%"  set "system=System32"  if /i not "%PROCESSOR_ARCHITECTURE%" == "x86" (     set "system=SysWOW64" )  echo Using: %system%  "%SYSTEMROOT%\%system%\cscript.exe" //nologo "%jsfile%" if not errorlevel 1 (     echo No error detected.     goto :done )  >nul 2>nul net session if errorlevel 1 (     if not exist "AutoItX3.dll" if not exist "AutoItX3_x64.dll" goto :done     echo Require to run as admin to register any dlls.     goto :done )  if exist "AutoItX3.dll" (     echo Register AutoItX3.dll     for %%A in ("/u" "") do (         "%SYSTEMROOT%\%system%\regsvr32.exe" /s %%~A "AutoItX3.dll"     ) )  if exist "AutoItX3_x64.dll" if exist "%SYSTEMROOT%\SysWOW64" (     echo Register AutoItX3_x64.dll     for %%A in ("/u" "") do (         "%SYSTEMROOT%\System32\regsvr32.exe" /s %%~A "AutoItX3_x64.dll"     ) )  :done del "%jsfile%" 

I suspect the AutoItX3.dll is not registered, which outputs a COM error.

The code above is batch-file, so you could save it as e.g. autoitx_comtest.cmd. It uses JScript to try to load the AutoItX3.Control object. If it fails and the script is running as admin, it will register the dlls if exist in the directory.

AutoitLibrary usually only provides the 32 bit dll, which is AutoItX3.dll. If you want 64 bit as well, add AutoItX3_x64.dll to the directory to be registered. If you have AutoIt3 installed, then you may already have the dlls registered by the installer.

If you have Python 64 bit installed, then AutoItX3_x64.dll may be required to use AutoItLibrary with it as 64 bit executables cannot use 32 bit dlls and vice versa.

Note: If you know how to register dlls with regsvr32, then you could just use that instead of the batch-file.

Compatibility with additional dlls

For compatibility with AutoItLibrary using an older version 3.3.6.0 of AutoItX3.dll. I could recommend using dlls from the archived versions and downloading autoit-v3.3.6.0-sfx.exe to get the dlls. In the latest AutoItX version, some methods were removed, such as RegRead. Also, the AutoItLibrary author may not support any version other than 3.3.6.0.

If you have the latest AutoIt Installer installed, then you may need to unregister those dlls and ensure the 3.3.6.0 dlls are registered to be compatible. I am unsure if you can have different versions of the dlls registered at the same time, on the same system.

The latest version of AutoItX dlls may work quite well, but AutoItLibrary keywords listed in the Documentation, such as Reg Read, Reg Write and some others may not be available as the methods were removed from the latest versions.

Latest vs compatibility, your choice.
