pywin32 Illustrator Throwing Exception Error - matthewsjc1 - Aug-26-2021

I'm trying to use pywin32 to access Adobe Illustrator through COM. I'm able to access other apps like Photoshop and Excel fine, but no matter how I try to access Illustrator, it always throws the exception: (-2147221005, 'Invalid class string', None, None).

The code:
import win32com.client as win32com
illApp = win32com.Dispatch("Illustrator.Application")

I can use the same code with other COM apps and it works fine. Does anyone have any suggestions?

Thank you!

*PS This is my first post in this forum. I'm a long-time programmer (C/C++, .Net, etc) and recently started using Python for some projects at work. So far, I'm really liking it!

Please show entire, unaltered error traceback . Please use bbcode error tag.

I hope I did this right. I'm using VS2019 with Python 3.7.8

I'm sorry. I'm new to this. I misunderstood what you meant. I ran trackback.print_tb() and got:

Error:]Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Is this what you were asking for Larz60+?

RE: pywin32 Illustrator Throwing Exception Error - Larz60+ - Aug-26-2021

For the error, yes.
But there's more code?

I actually figured out the issue! Illustrator's installation was either corrupt or that version (24.0.2) doesn't register its COM correctly. I installed a copy of the newest version and everything works perfectly.

Thanks,
Jared
