Symptom
Preactor 11 does not start when installed on Windows Server 2003 R2.
Cause
Preactor 11.0 RTM requires Microsoft .NET Framework 3.5 SP1 in order to run. The required framework should be installed by the Preactor installer, if it does not already exist on the machine. However, the Preactor 11.0 RTM installer fails to install Microsoft .NET Framework 3.5 SP1 on Microsoft Server 2003 R2.
Conditions
If
only Microsoft .NET Framework 1.x is installed, Preactor will fail to install, displaying the error shown below:
Error 1304. Error writing to file Preactor.Interop.EventScripts.dll. Verify that you have access to that directory.
If only Microsoft .NET Framework 2.x is installed, Preactor will install, but not launch.
Solution
Ensure Microsoft .NET Framework 3.5 SP1 is installed prior to installing Preactor 11 RTM.
