Hi,
Sometimes registry cleaners, defragmentation, or other such actions can disrupt the installation of any software.
A first step whenever any software won't run properly is to try restarting the software.
If that doesn't work, try rebooting the machine.
If that doesn't work, try reinstalling the software. If you need the download link for your Notation Musician software, please let me know at
support@notation.com
If none of the above fix the issue, then we can explore further.
ttfn,
Sherry
