The only file I have in "c:/user/yourname/appdata/roaming/bandlab-assistant/downloads" is asistant.exe and is 48MB. I don't like not having the download not stored locally.
I agree and have found a workaround below. The reason you only found that one file in the downloads folder is the install file named cakewalk.exe was deleted after it installed.
Here's what's going on:
When you install CbB versions, you can find the cakewalk.exe in C:\Users\xxxx\AppData\Roaming\bandlab-assistant\Downloads\cakewalk.exe
The trick is after it's downloaded, a window pops up asking to install CbB. First copy the cakewalk.exe to a new folder marked 2018 07 and then choose yes to install CbB. After it installs it will delete the cakewalk.exe file in your download folder.
This way you can easily roll back to a previous version. In addition to this I also save an image file of my C drive, so I can roll back that way also.
hopefully in the future Bandlab will make it easier to have access to previous versions.
