I have successfully deployed both 0.9.0 and 1.0.1 on dozens of computers. The trick is as follows:
- Install 0.9.0
- Rename C:\Program Files\Dyno to something else, I use Dyno090.
- Install 1.0.1
- Rename C:\Program Files\Dyno to something else, I use Dyno101.
- In C:\ProgramData\Autodesk\Revit\Addins\20##, you need to edit each Dyno20##.addin file.
a. Open .addin file in Notepad and change the directory in the Assembly to match your new folder name.
