SVEDBERG & DCDT+ installation issues

Remember, these programs require version 3.5 of the Microsoft .NET framework to be present on the installation computer prior to their installation. If you are running Windows 10, where .NET frameworks are part of the operating system, you will want to check whether .NET 3.5 has been activated before you try to install the program (see instructions below).  If needed, the program installer should detect this (before it does anything else) and try to open a Microsoft web page from which you can download and install it before the installation continues, but it may give an error message instead. If so there is a local copy of the .NET 4.0 installation package here, or this link should take you to the correct MS download page.

bulletHow to activate .NET 3.5 in Windows 10: Open Settings and click on 'Apps'. On the right side click on 'Programs and features' under the 'Related settings' heading (you may need to maximize the Settings window in order to see this item). This will bring up a new Control Panel window with a list of installed programs. On the left side of that list click on the 'Turn Windows features on or off' item. This will bring up yet another dialog box with a list of optional Windows features. Near the top of that list is the '.NET Framework 3.5 (includes .NET 2.0 and 3.0) item. If needed, check the check box for that item, and then click 'OK'. Your computer may then need to download additional files from the Microsoft web site to activate .NET 3.5 (it will do this automatically if needed).

If you are unable to download the normal installation executable file (dcdtinst.exe for DCDT+, svedinst.exe for SVEDBERG), possibly the download 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_exe.zip or svedberg_install_exe.zip, instead. Those .zip archives simply 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.
