  • .NET 2.0 SP2

    In Windows Server 2008 R2, the .NET 2.0 Framework is installed by default. No further action is required.

  • .NET 3.5 + SP1

    The .NET 3.5 Framework is already installed on Windows Server 2008 R2, but it needs to be enabled.

    2. Navigate to: 
      C:\WINDOWS\Microsoft.NET\Framework64\v3.0\Windows Communication Foundation\
    3. Enter the following and press Enter

  • PHP 5.5.21 and PHP Manager for IIS

PHP 5.5.21 and the corresponding Visual C++ Redistributable for Visual Studio 2012 is required for Perception 5.7.

Running 32-bit applications in 64-bit IIS

If you are planning to run 32-bit applications (i.e., Perception) in a 64-bit version of IIS, you will need to ensure that the correct settings are enabled. The settings are enabled by running specific commands and parameters from the command line. You will need to launch the command line prompt as an administrative user (you can do this by logging in as an administrative user or by right-clicking on the command prompt icon and clicking Run as administrator).

To enable 32-bit applications to run in 64-bit IIS, enter the following command at the prompt:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1

To enable the 32-bit version of the .NET 2.0 Framework for use with Perception, you will need to run the following command:

%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

...or, if that is unavailable, try:

%SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
