SVEDBERG & DCDT+ version 2 installation and registration issues
Remember, these programs require certain versions of the Microsoft .NET framework to be present on the installation computer prior to their installation. Which versions will work depends on your version of Windows. See the download page for details about installing .NET.
If you are unable to download the normal installation executable file (dcdtinst.exe for DCDT+, svedinst.exe for SVEDBERG), it is possible it is being blocked due to security settings for your network or your own computer. If so you can try downloading these .zip archives, dcdt+_install.zip or svedberg_install.zip, instead, which just package those executable files.
Installation and registration requires Administrator privileges on multi-user operating systems (XP, 2000, NT, Vista, Win7, Win8). Generally you will want to do a 'For everyone' installation. Other users on that computer will be able to run the program from restricted or non-restricted accounts.
SVEDBERG 7.0.1 note: The installer incorrectly put this version into a folder named 'SVEDBERG 7.0.1' rather than 'SVEDBERG'. After upgrading from this version you may need to manually move the file 'svedberg.lic' from that folder into the SVEDBERG folder (and then you can delete the 7.0.1 folder).
Registration note: Under Windows 7 and 8 (and possibly Windows Vista) being logged in as an administrator might still not give the necessary access privileges to write the license file into the program installation folder. If registration fails, try using Windows Explorer to navigate to the installation folder (usually in the Program Files folder), right click on the program executable file (DCDTPLUS.exe or SVEDBERG.exe), and select 'Run as administrator'. After you have registered you can then just start the program normally (from the icon or the Start menu).
DCDT+ version 2 Upgrade note: installation of DCDT+ version 2 does not un-install versions 1.xx. If you will no longer be using version 1.xx use its un-install icon to remove it.
