Hello,

I've been trying to install Houdini 20.0.506 launcher for the past two nights and I simply can not get past this error when running the "install-houdini-launcher.exe". I am on Windows 11 Version 10.0.22631 Build 22631. I have tried setting permissions on the folders, I've removed previous Houdini/launcher versions, etc.

Anyone else have this issue or can point me to what I can do to fix it please?

Thanks

If you contact support@sidefx.com they can help you out with install issues. Take care!

I used to get this because I was ticking all the addon boxes try uncheck and do standard install as it comes everything else can get added later make sure you have your licence set.

Turn off your antivirus before updating or installing Houdini Launcher.
