Cannot activate AutoItLibrary - Class not registered

According to AutoItLibrary support this error needs to be adressed by RIDE: When activating Autoitlibrary I get these messages (Klasse is niet geregistreerd = Class not registered):

Initializing test library 'AutoItLibrary' with no arguments failed: com_error: (-2147221164, 'Klasse is niet geregistreerd', None, None)

Is this indeed a RIDE problem? I am on RIDE 2.0b1 and Python 3.7.9

Hoi @Harm10 , I think I was able to reproduce your issue, but I was not able to link it to an issue in RIDE. I used autoitlibrary 1.2.7, and got a slightly different error (and in English rather than Dutch 😉 com_error: (-2147221005, 'Invalid class string', None, None) with a nearly identical traceback.

It could be that the installation of the AutoIt library was not completed successfully. During installation a dll is copied to C:\RobotFramework\Extensions\AutoItLibrary\AutoItX3.dll and then registered. I get this error when the registration part fails.

To fix this:

• Open Windows Explorer (verkenner)
• right click on the DLL and choose open with…
• Click Look for an other app on this PC and select C:\Windows\System32\regsvr32.exe
• You should get a pop-up telling you the DLL was registered. Click Ok
• Restart RIDE

Can you please check to see if this resolves your issue?

Thank for the update @Harm10, with this info I will close the issue here.
