CryptoPrevent v8.0 requires the Microsoft .NET Framework 4 Client Profile.  This is available for Windows XP SP3 to Current versions of Windows (Vista, 7, 8, 10) and is normally available through Windows Updates if it is not already built into the OS as it is in later versions.  You can also download the client profile here if you would like to manually install it.

Both CryptoPrevent v7.x and v8.x function on all versions of Windows (Windows XP will require Service Pack 2 to be installed) however the Program Filtering (“BETA” protection in v7.x) requires Windows 7 or above in order to be enabled.  On versions below Windows 7 the Program Filtering setting is unavailable.

Error:  (All Versions)  Unable to execute file in the temporary directory.  Setup aborted.  Error 5:  Access is denied.
This error is usually caused by existing anti-virus or security software.  We received confirmation that ESET Smart Security (with HIPS enabled) will cause this issue.  The resolution is to temporarily disable the HIPS component prior to installation.  There may be other security software with the same or similar issue but that is unconfirmed at this time.
