Heres a solution to my own issue when downloading packages from the website https://www.dynamopackages.com/.
Firstly, placing the files that come in the zipfile into the correct folder.
C:\Users\YOUR USERNAME\AppData\Roaming\Dynamo\Dynamo Core\1.1\packages
Beyond that there was the issue of these file all be blocked:
Rather than manually going through the 106 files that were in the “LinkDWG” package that I was installing I instead hunted for a way to automate this.
Powershell was the way to go for me:
$files = Get-ChildItem “C:\Users\YOUR USERNAME\AppData\Roaming\Dynamo\Dynamo Core\1.1\packages\YOUR PACKAGE NAME\WHATEVER FILE YOU WANT TO RUN THROUGH”
foreach ($f in $files){
powershell.exe -Command Unblock-File -Path $f.FullName
}
I likely did this in an inefficient way but i’m a noob to both dynamo and powershell.
Good luck everybody!
