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.

For Windows 10 (and especially if running it under Parallels) you may need to explicitly turn on or install .NET version 3.5 (which includes version 2.0 backward-compatibility). Under Settings, search for 'Programs and features' and then click on that. In the window that then comes up on the left you will see 'Turn Windows features on or off'. Click on that, and in dialog box that comes up find the section labeled '.NET framework 3.5 (includes .NET 3.0 and 2.0)', which should be near the top of the list, and be sure that .NET 3.5 is installed and enabled.

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.

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.

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.
