Ansys Python manager issues

### 🔍 Before submitting the issue

- [x] I have tried the latest Ansys Python Installer version
- [x] I have adapted properly the title of the issue

### Description

1/ when launching the manager, il flickers for a few seconds before opening

2/ when user manually updates the manager from File / Check for updates, the shortcuts in All Programs is not updated, so it still opens the previous version. Shouldn't the update actually remove the older version ? So it seems to be best to uninstall and install again. I did not check with the latest installer as it can not be updated
