****** VUSC Installation Version 6.50 ******


Installation prerequisites:

- Direct X version >= 9.0c
If you install on Windows XP check the DirectX version in your system. It’s very likely, that DirectX is already installed in your system. Check its version by running the program dxdiag.exe, usually located in C:\WINDOWS\SYSTEM32 or C:\WINNT\SYSTEM32. If there’s no DirectX or a version older then 9.0c download it from http://www.soft32.com/ (search for “DirectX 9 Redistributable”) and follow the instruction for the installation.

- The INSTALLATION DIRECTORY PATH must NOT contain any SPACES, DOTS or HYPHENS.

- If you want to use parallel LPT port for CW, rotator or bandswitch control you can optionally install DLportIO driver by running Install.exe from the subdirectory DriverLINX\install after the VUSC installation. Otherwise the driver installation IS NOT NECESSARY. This option works ONLY FOR 32-bit Windows systems.

- For the rotor control over USB install the MBUSBprt driver as described in the manual. This option works ONLY FOR 32-bit Windows systems.

Remarks:

The old *.DIX files from the DOS VUSC version can be read, but they are automatically converted to the new Windows format when saved and can not be used by the DOS version any more.

For the upgrade to a higher version you can download the archive VUSC_setup_<version number>_en.exe containing just the changed files. If you experience problems with the start after the upgrade replace the file vuscwin.cfg with the one from the subdirectory data or use some of the configuration templates vuscwin*.cfg as described in the manual. In this case you have to renew your private setting, though.

On Windows Vista/7/8/10 run the program as Administrator by right clicking on VUSC.EXE.

In rare cases the program may crash after the start. A bug in the sound card driver was indentified as a most common reason. The driver crashes when a certain DirectX function is called. In such a case start the program from a command line "Start->Run" with the argument nosnd and/or change the shortcut properties:

vusc.exe nosnd

It switches off the sound card entirely. The funtions depending on the sound card can't be used (SSB CQ call, CW monitor and audio recording), but the CW keying works OK.

If you have installed the DLPortIP driver for another application in your 64-bit Windows or there's an old version after the Windows upgrade it may cause problems with the start. Use the parameter nodlp in that case:

vusc.exe nodlp

If you want to use Microham the USB-driver (delivered with the Microham) must be running and the appropriate
virtual COM ports must be created before the start of VUSC.
