+
+**When does this issue occur?**
+
+If your systems' [ServicePointManager](https://docs.microsoft.com/en-us/dotnet/api/system.net.servicepointmanager.securityprotocol) is configured to use an out-dated security protocol, such as, TLS 1.0.
+
+**How can this issue be fixed?**
+

+
+```powershell
+[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
+```
+
+### Running scripts is disabled
+
+```
+PS C:\> iwr https://deno.land/x/install/install.ps1 -out install.ps1; .\install.ps1 v0.2.10
