This technical note provides information about installing and running Reflection 2011 or 2008 products on Windows XP.
Reflection 2011 and 2008 are certified and optimized for Windows 7. These Reflection products also support Windows XP (and Windows Server 2003).
For the best product performance and user experience, see Technical Note 1939 to help determine which product family is appropriate for your particular workstation and host environments.
When you run the Reflection installer (setup.exe), the wizard determines whether certain required system components are present, and will automatically install them if necessary. This prerequisite software is distributed with Reflection:
Windows Vista already includes .NET 3.0 and a later MSI version. On Windows XP, installation time may be longer if the prerequisite system software needs to be installed.
To reduce installation time, temporarily disable anti-virus software real-time scanning features.
Reflection 2011 and 2008 are built with Microsoft .NET technology. When launching any .NET application, a number of factors can affect startup time, such as hardware capabilities (as described in Technical Note 2324).
To reduce startup time of the Reflection Workspace frame, Reflection 2011 R1 and Reflection 2008 R1 Service Pack 1 (SP1) include performance enhancements that optimize assembly loading. Depending on the environment and application usage, cold startup time for the Workspace may be reduced up to 50%.
The original Reflection 2008 R1 release also includes the pre-loader and NGEN improvements described in the next section.
To reduce the startup time of Reflection for IBM 2007 on Windows XP systems, the following additional approaches are available. Note: Reflection 2011 and 2008 already include the following features.
To improve Reflection 2007 cold start time on Windows XP, pre-loader functionality is included in Service Pack 3. After the service pack is applied, a portion of Reflection for IBM 2007 (the Workspace) goes through the JIT compiling process at boot time. Depending on the environment, application cold startup time may be reduced up to 35-50%.
The Microsoft .NET Native Image Generator utility (Ngen.exe) pre-compiles the application at install time, slightly improving the warm and cold start times.
A hotfix can be applied as an MSP patch to an Administrative Installation of Reflection 2007 prior to application deployment. For more information on applying a patch to an Administrative Installation, see Technical Note 2255.
The pre-loader and NGEN fixes can be combined. In some Windows XP system configurations, this may provide the best cold and warm startup performance. Reflection 2011 and 2008 already include both startup performance improvements.
