Running both Windows Versions; 1 and 3

Hearing that the general release of Scrivener 3 for Windows is weeks away I download the latest beta and installed it. Now I have 2 Scriveners running; Scrivener Windows 1 and Scrivener Windows Beta. I was able to convert an old Scrivener 1 into Scrivener 3 (2.95xxxx).

Surprisingly, they both still run. Granted I installed the 64 bit version so I did expect both to startup but found that both work.

My question is this: Will there be an uninstall doc for Scrivener 1 so I can be sure it is gone from my system?

Thank You.
