Toggling from V4.x to V21.x
Version 21.x can be installed independently of Version 4.x, and both can co-exist in parallel on an SAP server during the transition to Version 21.x.
When using V4.x, please follow the following steps to disconnect from V4.x and connect to V21.x:
1. From Excel –> File –> Options –> Add-ins –> Go, untick the V4.x add-in: Wands (SAP)
2. Close Excel
3. Logon to V21.x as usual
