Hello nest89 -
The error "Could not load transport DLL mwmtrans.dll" occurs when there is either another program is using the file mwmtrans.dll or an anti-virus application is blocking it.
The 3Dconnexion software needs to be installed installed from a profile with full administrator privileges.If this is a network PC and you do not have full administrator rights, an IT tech would need to do the installation.
To resolve anti-virus conflicts you can create an exception in the anti-virus application settings for the driver executable - 3DxSrv.exe. [C:\Program Files\3Dconnexion\3Dconnexion 3DxSoftware\3DxWare\3dxsrv.exe]
We have seen conflicts with Bitdefender on Win7. If you have Bitdefender 2010, change your scanner settings to "Tolerant". If you have Bitdefender 2009, disable "IDS instrusion detection system" in advanced firewall options.
If you are installing the software from CD, you should instead download the current software from our web site at
http://www.3dconnexion.com/support/downloads.php
Save the software to your PC then make sure you are logged in from an administrator profile.
To resolve the error " Could not load transport.." it is important to make sure all background applications are closed during the installation. One type of applications known to interfere in this way are programs to configure your standard mouse such as the MouseImp program. You need to turn the software off during the installation then you can turn it back on after the 3Dconnexion device is installed.
This type of background program can be turned off either from its SystemTray icon or using msconfig to temporarily prevent it starting.
Thank You,
Fred
