Hello.
I am teaching a user how to use D5. I am still using version 2.11 because the plugin for ARCHLine has not been updated yet.
The user, on the other hand, has installed version 3.0, so the two programs cannot be synchronized. I downloaded the previous version (2.11) for the user from this link:
However, when I tried installing it on my other computer, the installer does not work and the program does not install.
I disabled everything as you wrote, but I still can’t install the program. Even when I run it as administrator, I get to this window and after clicking “Yes”, nothing happens.
I downloaded the program from the link you provided.
