Issue Description

You have installed the Rainbow Desktop App and get following missing Qt5Core.dll error message when starting the app

Root cause:

a possible reason for this is that on your Windows PC, the files with extension .vbs are not associated to Microsoft ® Windows Based Script Host

Most of the time in error case, the file extension .vbs has been associated to Notepad instead of Microsoft ® Windows Based Script Host. This wrong association will prevent execution of some installation files and result in the issue described above

How to fix this issue:

To fix this issue you just need restore the good file association for file .vbs extension.

• Open Set default programs in Windows Control Panel
• find the entry .vbs and click on Change Program, then Select Microsoft ® Windows Based Script Host
• Click OK.

• If Microsoft ® Windows Based Script Host is not in the list you have to browse to C:\Windows\System32\ to find the program wscript.exe and select it.

• And last step is to uninstall Rainbow Desktop app and then to reinstall it.
