Hi,
The CVI Run-Time Engine does not provides an individual installer; the required dlls are installed by the IDE. There is a possibility here; you may want to downgrede the CVI run-Timeengine installed to see if these font effects go away. You can go to the windows\system32 folder and delete the cvirte.dll from there and delete the cvirte folder as well. Then you can download the CVI run-time engine installer from the web.
I hope this helps.
Regards,
Juan Carlos
