GUID not working when client.GetActiveObject is None

[theobinomy]

I'm running this script below. When I run it the first time, it should create a new instance of a program. When I run it a second time, it should be attaching to an already running instance. Instead it creates a new instance. The only thing that has changes was a windows update. I have tried running the code with Comtypes version 1.1.3, 1.1.4, and the current master.

Code:

def launcher():
    import comtypes.client
    try:
        #trys to attach to a running instance
        mySapObject = comtypes.client.GetActiveObject("CSI.SAP2000.API.SapObject")
        SapModel = mySapObject.SapModel
        return mySapObject, SapModel
    except OSError:
        #if no running instance, creates new instance
        print('os error')
        helper = comtypes.client.CreateObject('SAP2000v19.Helper')
        helper = helper.QueryInterface(comtypes.gen.SAP2000v19.cHelper)
        ProgramPath = 'C:\Program Files\Computers and Structures\SAP2000 19\SAP2000.exe'
        mySapObject = helper.CreateObject(ProgramPath)
        mySapObject.ApplicationStart()
        SapModel = mySapObject.SapModel
        SapModel.File.NewBlank()
        return mySapObject, SapModel
if __name__ == '__main__':
    a, b=launcher()
    print(a,b)

Looking into this some more, the SAP2000v19.py object is in /comtypes/gen, there is nothing comtypes/client. On the first time I run the program I can run a lot of commands using the same object. the control object stick around, so I can continue to issue commands while the initial window is open. When I close it, and reopen it is impossible to issue new commands.

I was able to solve my issue, using the solution presented here: https://techtalk.gfi.com/32bit-object-64bit-environment/

If there is a way to incorporate this into the code, it would be great.
