DCDT+ version 2 installation issues

Remember, this version requires Windows 98 or newer operating systems.

It also requires the Microsoft .NET framework version 1.1 to be present on the installation computer prior to installation of DCDT+. This is normally already true for Windows XP systems. If it is not already present, this should be detected during DCDT+ installation and this link given so .NET can be downloaded from Microsoft and installed. Version 2.0 of .NET is not backward-compatible with version 1.1, so you will have to load 1.1 as well as 2.0 if 2.0 is already present.

Installation and registration requires Administrator privileges on multi-user operating systems (XP, 2000, NT). 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.

UPGRADE note: installation of 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.

SVEDBERG installation issues

Common installation issues

Multiple users on one computer

If you are going to have multiple users logging onto a single computer under Windows NT, 2000, or XP, then each user must install and register the program (remember a single license covers multiple users). It will not work to do a single 'administrative' install to cover all users on that computer.

Errors during installation

On some computers the installation has failed with an error message "cannot copy SETUP1.EXE". This is caused by some prior software installation that violated Microsoft conventions. The SETUP1.EXE files are a common part of standard Microsoft installation routines, but they are supposed to be deleted at the end of the installation. The error is occuring because some installation left a SETUP1.EXE file, and left it marked as 'read-only' so it cannot be over-written.

The work-around for this problem is to manually delete the file SETUP1.EXE from the main Windows folder (normally c:\windows).

False "expired trial period" messages and failure to retain individual program defaults

These issues arise when multiple users log onto a computer running Windows NT, 2000, or XP. Because of the way Microsoft implements multi-user support, the information about program registration, the trial period, and program defaults is associated with a particular user, and is not available to other users.

Thus when a different user logs on the program cannot find the registration or trial period information and will give an "expired trial period" message and refuse to run, even though the program has been installed less than 30 days or even after the license information has been entered on that computer.

Therefore it is necessary for every user to install a trial copy and/or go through the registration process while he/she is logged onto that computer. (Sorry, but this is a problem Microsoft created.)

The good news is that this allows each user to have his/her own preferences and defaults, independent of those for other users on the same computer.
