Could not install the project on windows 7

[m-ahmadi]

Question
I tried to install the project on windows following the instructions from this page where I got these 2 error message in my PowerShell window.

Here's what I ran:
Set-ExecutionPolicy Bypass

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; iex ((New-Object System.Net.WebClient).DownloadString('https://wiki.js.org/install.ps1'))

Here are the error messages:
Exception setting "SecurityProtocol": "Cannot convert null to type "System.Net.SecurityProtocolType" due to invalid enumeration values.
Specify one of the following enumeration values and try again.
The possible enumeration values are "Ssl3, Tls"."
At line:1 char:28

• [Net.ServicePointManager]:: <<<< SecurityProtocol = [Net.SecurityProtocolType]::Tls12; iex ((New-Object System.Net.WebClient).DownloadString('https://wiki.js.org/install.ps1'))

In an elevated powershell prompt:

# For x64:
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

# For x86:
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord 

Then try again in a new powershell prompt.

I tried your solution and got the same 2 error messages.
still unable to install.

Then I suggest downloading the script manually and executing it locally:

https://wiki.js.org/install.ps1

[m-ahmadi]

I downloaded the script and ran:
powershell -executionpolicy bypass -File .\install.ps1
and
Set-ExecutionPolicy Bypass
powershell -File install.ps1

both in normal and elavated prompts, and here are the error messages:

`Exception setting "SecurityProtocol": "Cannot convert value "tls12, tls11, tls" to type "System.Net.SecurityProtocolType" due to invalid enumeration values. Specify on
e of the following enumeration values and try again. The possible enumeration values are "Ssl3, Tls"."

It seems like your version of Windows is too old for this script. Try installing the app manually:

• Download both:
  https://github.com/Requarks/wiki-v1/releases/download/v1.0.117/wiki-js.tar.gz
  and
  https://github.com/Requarks/wiki-v1/releases/download/v1.0.117/node_modules.tar.gz

• Extract the contents of wiki-js.tar.gz to a folder of your choice.

• Extract the contents of node_modules.tar.gz to that same folder.

• Rename config.sample.yml to config.yml

• Run node wiki configure

My Windows version is: Windows 7 Ultimate Service Pack 1

This solution worked and I was able to install and use the project. Thanks a lot!
