In case you do not get an image from the FOculus camera which comes with the RheoScope module in RheoWin, please download and install the newest driver for this camera from the camera manufacturers web-site using the link below.

Due to a Windows Update (from Microsoft) the Direct X support of the camera driver didn’t work anymore. This was fixed by the manufacturer with a new driver version.

Installation of RheoWin 4

RheoWin 4 can be installed parallel to an existing RheoWin 2.xx installation and/or an existing RheoWin 3.xx installation if needed. Please note that RheoWin 4 can read RheoWin 2.xx and RheoWin 3.xx data, job and page files (backward compatibility), but that RheoWin 2.xx can NOT read RheoWin 3 files and that  RheoWin 3.xx can NOT read RheoWin 4 files!!

RheoWin 4 should never be installed in the same directory as RheoWin 2.xx or RheoWin 3.xx!!

The installation program of RheoWin 4 offers the user the possibility to transfer all settings (apart from the Unit settings) from a previous installation of RheoWin 3.xx.

Here's how to install RheoWin:

  1. Please note that (Windows) Administrator rights are needed to install RheoWin!
  2. From a directory on your harddisk in which you unzipped the *.ZIP files:
    To install RheoWin from harddisk go to the (temporary) directory in which you unzipped the *.ZIP files after downloading. Please make sure that you have the following 7 files in that directory : HAAKE RheoWin.msi, Setup.exe, Data1.cab, 1031.mst, 1033.mst, 1034.mst, 1036.mst, 1043.mst. To start the installation please run the Setup.exe program.
  3. From the RheoWin CD:
    This CD is "self-starting", just click on "Install HAAKE RheoWin 4" to start the installation. In case the installation screen does not come up automatically you can start it by double-clicking on the file "index.htm" in the Windows explorer, this will show the installation screen in your web-browser. You can also start the installation by run the setup.exe program from the RheoWin directory on the CD

The installation program will guide you through the installation. Please make sure that you have a RheoWin 4 License Key (see above) readily available since the installation program will ask for this.

RheoWin and Windows users (Administrators, PowerUsers, Users, etc.)

Windows users with the default Administrator or PowerUser rights will be able to run RheoWin without the need for any modifications.

For Windows users with the default Users rights an Administrator has to make sure that those users have read access to the RheoWin 4 main directory (by default c:\Program Files\Thermo\RheoWin) and all its subdirectories, as well as read and write (!) access to the


key in the windows registry and the following two directories and all their subdirectories

C:\Documents and Settings\All Users\Application Data\Thermo\RheoWin
C:\Documents and Settings\All Users\Documents\Thermo\RheoWin.

Microsoft advices programmers to save application and user data in the above metnioned directories by default, but strange enough does not give Windows users with the default Users rights write access to these directories!
