It was up and running just a few days ago. Now shows error " mfc120.dll is missing". Got answer from you guys "Your Windows installation is incomplete. It should help if you install the missing Microsoft Visual C++ Redistributable". Tried but does not work.
Try a system restore point prior to the issue. Temporarily disable anti virus the see if the has something to do with it. Reinstall SF, it should also ask if you wish to reinstall the.dll file if it's missing.
In general, you should specify what version of SF you are using Read the 'Sticky' at the head for the main Sound Forge forum page.
btw, welcome to the Magix Sound Forge users forum @Jeff-Nunn,
