iex cannot convert Tls12 to type System.Int32

[femrich]

I am running windows 7, sp 1, checked for updates and loaded PS yesterday. From the PS command line I am running the command:

iex (new-object net.webclient).downloadstring('https://get.scoop.sh')

But I receive the following error:

Invoke-Expression : Cannot convert value "Tls12" to type "System.Int32". Error: "Input string was not in a correct format." AT line:24 char: 1
+Invoke-Expression (new-object net.webclient).downloadstring($core_url)

• CategoryInfo : InvalidArgument: (:) [Invoke-Expression], RuntimeException
• FullyQualifiedErrorId : InvalidCastFromStringToInteger,Microsoft.Powershell.Commands.InvokeExpressionCommand

Can you tell me please what this means and how to resolve it?

I am a non-tech person self-educated over years setting up and maintaining personal drupal sites, and doing this now to keep up with the requirements for drupal8. I have little to no experience with command line, but doing this to work with the now-required Composer. Any help you can offer with explaining and resolving this error and pointing me to resources to help me on my quest would be much appreciated.

Thanks.

Same issue in Windows 8.1:

Hey, please try this, and tell me if it works:

1. find scoop\lib\core.ps1

cd ~/scoop/apps/scoop/current/lib/

2. edit core.ps1, line 23 to 26:

from:

function enable-encryptionscheme($scheme) {
  [Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor $scheme
}
enable-encryptionscheme "Tls12"

to:

function enable-encryptionscheme() {
  [Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12
}
enable-encryptionscheme

Besides, what's the version of .NET framework your system installed? You should have .NET 4.5 and above installed to use TLSv1.2.

@h404bi yes your solution works, I had the same idea and created PR #2084 for the issue.

I tried this command in Powershell:

cd ~/scoop/apps/scoop/current/lib/

Got an error saying the file does not exist.

Searched my system for Scoop and all it came up with was a file in LibreOffice. I think my first error was indicating Scoop had not been downloaded, no?

@femrich yeah, you haven't install scoop successfully. Try this before this issue being fixed:

iex (new-object net.webclient).downloadstring('https://gist.githubusercontent.com/h404bi/e70ce87b0c523f33f2ff041a657a6182/raw/2e3c26d5e425531f23c292baf3e16f0b0e8dad68/install.ps1')

@h404bi as a result, Scoop was installed successfully! Thanks very much! I am looking forward to learning more about this tool and much appreciate the support from you and @milang !

Cheers!
