Installation of Visual Spec

This version is a major release - it will completely re-install Vspec, even if you previously installed older version. Open and run VSpec as admin if you encounter dll registration issues.

Make sure you run the installation with administrator rights, and run Vspec.exe as admin as well. If you see some ocx or dll reported as missing or unregistred, try to run Vspec.exe as admin the first time. To do this, right click on the icon, do not select "open" but "run as admin" in the context menu.

Vspec440 setup.exe 

  • Download in a temporary directory
  • Run the setup.exe in admin mode
  • Once installed, run vpsec.exe in admin mode to avoid message on dll or ocx unregistered

Having issues, questions or suggestions ? 

Despite my efforts, bugs or unexpected troubles may occurs. With the help of many of you, here are some tricks you can find useful... 

    Warning 1: never delete the directory which are indicated as the default directories for images or profiles. You will have to re-install Vspec. 

    Warning 2: if the message "VB6fr.dll est introuvable" appears make sure there is copy of the file in System32 or sysWOW64 directory, the file shall be in the vspec directory, if not get the file

    Warning 3: If you cannot run excel functions like finding spectral types or coordinates, make sure you authorize Excel application to run macros (Security levels)

    Warning 4: It seems that VSpec has issue when installed in another drive than c:/

    Warning 5: install in admin and run Vspec in admin (right click and select open as admin) if you have message telling some ocx are not properly registered.

    Warning 6: if you have some read/write issues with request to BeSS, or other strange folder forbidden access, try to install Vspec in root directory (aka not is program files folders) which maybe protected.
