Configuring the ThinApp Runtime 4

You can modify ThinApp parameters for runtime configuration tasks that affect application startup

performance and virtual computer names.

This chapter includes the following topics:

“NetRelaunch Parameter,” on page 15

“RuntimeEULA Parameter,” on page 16

“VirtualComputerName Parameter,” on page 16

“Wow64 Parameter,” on page 17

“QualityReportingEnabled Parameter,” on page 17

NetRelaunch Parameter

The NetRelaunch parameter determines whether to restart an application from the local disk when you run the

application from a network share or removable disk, to address the slow startup of applications.

ThinApp sets an initial value of the NetRelaunch parameter that detects whether an application runs from a

network drive or a removable disk, and uses a stub executable file on the local hard disk to restart the

application. This process addresses performance problems that Symantec AntiVirus generates when it tries to

do a complete scan of executable files that open from a network share or removable disk, and on executable

files that make the initial network connections. The scan can affect start times for large executable files.

Because a large number of desktop computers use Symantec AntiVirus, ThinApp enables applications to open

from a network share without incurring lengthy scan times. When the application runs from a network share

or removable disk, ThinApp creates a stub executable file in the directory that the CachePath parameter sets

on the local disk and restarts the application from this stub executable file. The stub executable file can load

the runtime from the large package and read the remainder of the application from its original location on the

network. Some AntiVirus applications perceive that the application is local, so does not scan the larger

executable file on the network share or removable disk.

Example: Modifying the NetRelaunch Parameter

This example shows how you can modify the NetRelaunch parameter for stronger initial startup performance.

Modify the parameter if your application is small or you know that Symantec AntiVirus is not installed on the

desktops on which you are deploying the application.
