Seeking Guidance for Clean NT8.1 Installation While Preserving Old Version
When you reinstall it will recreate the user folder you had just renamed with only stock files.
Now you can start the platform. Because there are no other items in this installation, only the item you want to export will be included.
Go into the Documents\NinjaTrader 8.Prev\bin\Custom\Drawing Tools folder, copy the .cs file you want to export, then paste that file into the respective new Documents\NinjaTrader 8\bin\Custom\Drawing Tools folder. Attempt the export after this.
To switch between the two installs; shut down NinjaTrader > rename the new installation to 'NinjaTrader 8.Dev' under (My) Documents > then rename the 'NinjaTrader 8 .Prev' to 'NinjaTrader 8'. NinjaTrader looks for the user folder named "NinjaTrader 8" specifically.

With this procedure i could keep two versions of Ninjatrader but it seems it is not possible anymore with version 8.1.
Apparently, we need to uninstall 8.1 and reinstall the old version if we want to revert back to a prior version.
That's a bit heavy. I'd like to keep both on my development platform without having to unstall and reinstall each time.
According to the support at Ninjatrader, here is the proper way to proceed:

It wouldn't be possible to have multiple versions of NinjaTrader installed at one time. However, there is somewhat of a way to switch back and forth.
The "NinjaTrader 8" folder in your documents folder contains all the information which makes NinjaTrader "yours" (workspaces, indicators, connections, etc). NinjaTrader will load from whichever folder is named "NinjaTrader 8" in your documents folder. You can have multiple folders in the Documents folder which you simply rename as you wish to switch. Switching between these folders and uninstalling/reinstalling with the respective download .msi file will allow you to accomplish what you desire.
Here is an example:
Shut down NinjaTrader
Rename your "NinjaTrader 8" folder within the Documents folder to "NinjaTrader 8 Original"
Uninstall and reinstall NinjaTrader with your desired version's .msi file - this creates a new "NinjaTrader 8" folder in the documents folder
Start NinjaTrader and configure it as you wish
To switch back:
Shut down NinjaTrader
Rename your "NinjaTrader 8" folder within the Documents folder to "NinjaTrader secondary"
Rename the "NinjaTrader 8 Original" folder within the Documents folder to "NinjaTrader 8"
Uninstall and reinstall NinjaTrader with your desired version's .msi file
With this process, just bear in mind that will have to uninstall and reinstall with your desired version as indicated by the steps above, because it is not possible to have both 8.1 and 8.0 installed at the same time. If you want both at the same time, it would require you to have 2 different PCs to be able to run 2 different installations.
WOW,
I've used a similar process (as you have) on 8 prior to the new 8.1 by renaming the file in Documents.
However, it never required uninstall and reinstall NT to swap. Just changing the name in the folder was sufficient.
This is terrible.
For me, the only solution is to either use a sandbox or install 8.1 on a different pc which is very difficult to do development etc.

Yesterday, I explored the sandbox alternative, but I'm uncertain about its usage on the site. Do we simply need to copy the NT8 folder into a partition or another directory that the sandbox manages? I'm unsure about the process.
