ProAchieve is used by The Registry and FE academics.
The client does not support switching between live and test database servers.
However a workaround is to uninstall the client in AppsAnywhere then reinstall the client for the required server.
Open Cloudpaging/AppsAnywhere icon bottom right
Highlight ProAchieve and click on Remove icon.
If both live and test are listed then it is best to remove both and only use 1 at time.
Wait for it to Validate.
search for ProAchieve
Launch the required client; live or test
