Hello from the past, to anyone who's facing this problem, this is what I did :
It took me many hours to fix it, when it was simple. My initial problem was that I tried to install MSI Center before installing Creator Center.
I :
- realize that the "DiagnosticTool" does not erase MSI Center SDK (yet it should)
- reinstall MSI Center to have the ability to uninstall MSI Center SDK
- uninstall MSI Center SDK (from Settings > Apps > Apps & features), then MSI Center (and Creator Center if you still have it)
- run DiagnosticTool to uninstall everything (we never know)
- install Creator Center
It worked for me! If not for you, you can try the other solutions below:
- run the app as administrator
- reinstall/uninstall the app
- disable antivirus, disable folders containing the programs
- disable MSI stuff in firewall
- use the MSI "DiagnosticTool" to erase everything and reinstall
- update all drivers
- start/modify the Windows service "MSI Center Service"
- download from Microsoft Store, from MSI site
- try other MSI apps (Dragon Center, etc., often not compatible)
Good luck!
