We'd recommend that you try to repair the most recent C++ Redistributable Libraries (likely 2015 and 2017) on your machine.
To perform this task:
- Open the Control Panel.
- Click Programs and Features.
- Select the program that needs to be repaired. (Microsoft C++ Redistributable 2015/2017)
- At the top, click Change.
- In the dialog box, click Repair.
If this does not help, remove BandLab Assistant via the Add/Remove Programs on Windows and reinstall the latest version of BandLab Assistant downloaded from here.
