Powershell Install Script Custom Path Error

[TheBrambleShark]

Hello,

When running the following command:

powershell -executionpolicy bypass .\dotnet-install.ps1 -InstallDir "C:\Program Files\dotnet" -Channel LTS

the following is output:

dotnet-install: Downloading link: https://dotnetcli.azureedge.net/dotnet/Sdk/Files\dotnet/dotnet-sdk-Files\dotnet-win-x64.zip
dotnet-install: Cannot download: https://dotnetcli.azureedge.net/dotnet/Sdk/Files\dotnet/dotnet-sdk-Files\dotnet-win-x64.zip

As you can see, the string concatenation somehow goes wrong, leading to /dotnet/Sdk/Files\dotnet/dotnet-sdk-Files... in the first file path.

System Information:
Windows 10 Professional 1909
Powershell environment: elevated PowerShell ISE (running as another user)

When no parameters are provided, the script runs exactly as expected, leading to the DotNet sdk installing under the user's profile. However, I instead want DotNet to install under C:\Program Files\dotnet so it is available to everyone.

Work-around: Installing with the .exe installer.

This might be an issue with the install directory containing a white space in it. Will check it out. However, for installing in a global location like program files, I would recommend using the windows installer instead of a install scripts.

Hello @Foxtrek64!
It seems this is a known bug of cmd.exe, related to passing strings with spaces to powershell. However, it is easy to work around it.
You could just use single quotes instead of double for the path:

powershell -executionpolicy bypass .\dotnet-install.ps1 -InstallDir 'C:\Program Files\dotnet' -Channel LTS

Here I also found some other ways to work around this. No work needed on the script, so I am closing this issue. Please do not hesitate to reopen it if this comment does not solve your problem.
