VidBlasterX is a native 64 bit program and requires a 64 bit version of Windows 7 or higher. Installing the program is straightforward and should not pose any problems. After installing a reboot may be required but only if you are prompted to do so. VidBlasterX can coexist with earlier major versions of the program, each will have their unique own folder and shortcut, enabling you to trial a new major version while continuing to use your current production version. Note that minor version updates will overwrite your current version.
Resetting the profile
Changes in Windows, in device drivers or hardware may prevent VidBlasterX from starting a (new) profile properly. If you hold down the left Shift & Ctrl keys while starting the program it will silently load the (empty) default profile instead of the last used profile. As a backup the old profile will be saved with the current timestamp.
