I tried to install 20.0 on Windows 10 without admin rights using the default path suggested. The desktop and start menu icons are linked to an executable which does not exist. When clicking on the Persalys icon: ![image](https://global.discourse-cdn.com/free1/uploads/persalys/original/1X/8d33f207368bae9c53556aee818c02a2ed934b80.png) Double clicking persalys.exe does also not start Persalys. ---

UPDATE: Security software from our IT deleted the persalys\_launcher.exe file upon installation. So this is **not** an issue with Persalys. With 19.1 this did not happen. I will try the install 20.0 with our IT and report if it does not work. ---

Hello, You can download Persalys 20.1 from the website, it should hopefully fix the issue. Regards, Antoine ---

Hi Antoine I have unfortunately the same problem with Persalys 20.1 We got around it by someone from the IT releasing the persalys\_launcher.exe from the security software quarantine. Now Persalys starts and works fine. Best regards, Reuben ---

I tried installing it in another directory but the same problem occured. My collegue actually had the same problem under windows 11 too. I think the security software which our company uses is maybe just too strict. ---

Yes we had some problems with a specific library that was classified as dangerous but we fixed it with the release 20.1. Can you have more info from your IT department what is happening ?
