I previously had Unity Hub around a year ago and uninstalled it. I went and deleted the old directory in the Program Files folder and then installed the newest version of Unity Hub. When I launched it, the old directory that I used to use for my old projects was already in the box. When I tried to create the project, it said "Unable to create project". Is there some other thing I'm supposed to delete also? I don't know where the old version used to save that kind of information, but I think it has to be deleted for the newer one to work. Unfortunately, I don't remember what version I had before. Any help would be great. Thanks
You should never delete software's files without uninstalling them. Try to uninstall Unity Hub with the apposite feature and re-install the latest version.

When I launch a project via Unity Hub, the following message is printed : Unity is already in list. You cannot locate the same version.
unity hub error
And when I want to access my project via Assets -> Scenes.
I get this : error message
If I said "continue", my project is broken with a lot of errors to fix.
Have you a solution ?
Thanks
From what I see in your screenshot, you are trying to open a project with an older unity version than the project's version. As it is written in the message, the operation is not supported and you should open it with at least the same version, or an older one. Make sure you have such a version installed in Unity Hub and to open the scene with this version.
You can still try to get everything to work by reimporting all you assets in Assets -> Reimport All but this will probably fail.
Recently I updated Unity from version 2020.1.0b6 to 2020.1.16f1, but after starting the project, I started getting errors, and all two versions, I tried to reinstall, nothing helps. Below are links to screenshots

Please open Package Manager from Window/Package Manager on the menu.
There, you will be able to find packages that are related to the issues.
And please try to remove or update the packages.
If it's possible, would you share a screenshot of your Package Manager?

I am trying this since past few days, and it has become annoying :(.. plssss somebody helpp.....
You should try this post:
Can't add modules to installed Unity editors
It says no reinstall required. But I would try that next.
It cannot hurt to read this as well:

I opened Unity for the first time in a while today and I'm unable to create new scripts of any type. Both the normal and right click menus are missing the option:
Adding a script through the inspector creates a file, but yields these errors:
Although the file is created, it does not appear in either the project browser, or inspector panels.
Googling various parts of these errors actually gets a lot of posts, but almost all of them come down to "restart Unity", which isn't doing anything.
All of this is reproducible for me on a fresh project file. I've tried restarting Unity and my computer, as well as reinstalling Unity from scratch. I've also double checked that I have .NET installed properly (reinstalled, and dotnet command works in terminal).
Unity: 5.4.5p5
Mac OS 10.13.3
This is a bug present in versions between Unity 5.1 and 5.4. It has been fixed in Unity 5.5.0 and an update to 5.5.0 and above should fix it.
If updating to Unity 5.5.0 which has the fix did not fix it then it's better to upgrade Unity to the latest version which is currently Unity 2017.4 at the time of posting this answer. This version should be able to get ride of that error.
I have a MSI assembly which is an upgrade. The Upgradecode remains the same between the previous release and the new upgrade assembly. I also have the RemovePrevious attribute set so old version is removed before upgrade is installed.
I see the uninstallation of the old version occur as expected. However, the Windows Installer 3.1 immediately turns around are attempts to re-install the old version again before it even proceeds to the new version. I have verified this by changing the first custom installation dialog in the newer version and see it just fine on a first install of the new version. But the dialog seen when upgrading is the old one which shipped with the previous release. I even rebuilt the old release with message box displays to verify that Installer is indeed re-installing the old version right after the uninstall rather than moving on to the new upgrade version.
Using MSIExec does not reveal any errors being logged to explain this odd behaviour and I cannot find any documentation that helps to identify why this is occurring.
Anyone have any ideas on why this behaviour is happening and how to go about fixing it?
Try increasing the version number of your app/dll in the embedded resources. The "new" behavior of the installer will not upgrade any exe/dlls unless the file versions have been bumped up.
