Hello,
I finished installing Sage 50 CA in my Windows 10 yesterday, but I couldn't open this program. Every time I click on this program, a message appears: "The available font, MS Sans Serif 8, may not be suitable. If the Home and transaction windows do not display correctly, use the Windows Control Panel to add fonts". Please tell me how to solve the cause and why this is happening.
Thanks,
Hae Dong
Hello Hae Dong Kim,
Thanks for reaching out. Please review this post "Font Error Message Upon Startup" that is similar to your issue.
Basically, the Steps to change the default font in Windows 10
Step 1: Launch the Control Panel from the Start Menu. 
Step 2: Click on the “Appearance and Personalization” option from the side menu.
Step 3: Click on “Fonts” to open fonts and select the name of the one you want to use as default.
Hope this helps!
Erzsi
