I have it installed for few days, but suddenly now it is not there.
PS C:\> scoop

when I try to install it again I'm getting the following message (hard to see as it crashes the powershell and exit, but able to get print screen)

scoop is already installed and try to update
Some additional errors when I try again

PS C:\>
It looks like scoop might have been removed from your path, but the directory is still there. You might want to check for C:\Users\[username]\appdata\local\scoop\shims in your user path.
It was there, and this above error came up when installing it fresh, so it shouldn't give any error I guess, so now I removed everything manually and trying to install it again, tx
Just following up鈥攄id it work when you tried installing again?
This error might also have been because your path environment variable exceeded the maximum length allowed by Windows.
I haven't found a good solution for this鈥攖he usual response seems to be "If your path is that long, you're doing it wrong". I think it's more wrong to have this arbitrary limitation for historical reasons that don't (or shouldn't) apply any more. The path is a well known and widely useful mechanism for having a list of directories to search. Why should it be limited on a modern computing system?
Scoop does try to avoid polluting your path by using shims, but a lot of programs just expect certain directories to be in the path. Of course that works fine when the programs are running on Linux or Mac OS.
I meet the same issue. I solved it by deleting "C:\Users[username]\appdata\local\scoop" then reinstall.
It seems that network error can cause the installation into a broken status: it tells you it's installed, but you cannot execute. In such case just delete the app folder and reinstall.
It works after delete the folder in local PC.
I met the same problem, and I find that the path is quite different in win7 as it is under C:\Users\UserName\scoop\apps\scoop, instead of under \appdata, and the deep scoop folder(under \apps) is empty, so I delete the whole scoop under \UserName and install it again using "iex ...", then it works.
I guess the problem is due to the failed installation of scoop during the first time and so it's empty, and when try to install again it says "Scoop is already installed" due to the exisiting directory. Meanwhile when using "scoop update", it has some warnings like "The term 'scoop' is not recognized as the name of a cmdlet..."
In my case, 'Path' in 'User variables for me' has been cleared, so I added to it ''C:\Users\
Yes adding shims to your PATH make it working again
Disappear for me after install pshazz prompt
Better to check it
Something is wrong there
I can make a issue there in its page
Just wanted to inform
