[ANSWERED] Isadora 2 no longer starts after Windows 10 update

[Pascal]

Hello,
I have Isadora 2.6.10 with a key on Windows 10.
I updated Windows and now Isadora won't start. I reinstalled Isadora and the key driver, but it still won't start. I don't understand.
Can you help me?
Kind regards

As I replied to your support ticket:

I just opened Isadora 2.6.1 on my Windows 11 machine and it appears to be working as expected. 
Do you have third party plugins/FFGL effect etc installed? You might need to Hide anything like that from Isadora (rename the folders.. I generally add '_HIDE' to the foldername) That way the externals won't be loaded the next time you open Isadora. 
You can also, try deleting your preferences file. It may be that something about your video config changed with the update, and this will reset things.
You can find the preferences at: C:\Users[YourUserName]\AppData\Roaming\TroikaTronix

I’m revisiting this post because I still haven’t found a solution, and I’ve done everything DusX told me to do… Isadora (2.6.10) won’t launch. I wonder if there might be an incompatibility with the Universal Audio audio driver? This has been happening ever since I installed it for a sound card.
Thank you for your reply

Could be. Have you tried removing it?

Just out of curiosity, could you download Isadora 4.1.3 and see if it launches? (Isadora 4 and Isadora 2 can be installed on the same computer without interfering with each other, and you can try launching Isadora 4 in demo mode, without a license, just to see if you have the same problem.)

 There was an issue in the past with a Nahimic audio driver, that wouldn't let Isadora open. Do you have anything by that name?

@woland hello, thanks for answer. I've install and lauunch Isadora 4 in demo mode without any problems.

@dusx hello, yes i have Nahimic

 If possible, update to Nahimic version 2, the issue was corrected in the new version.
If you can not upgrade, the only solution I know of is to remove/uninstall Nahimic cleanly.
