Create a Response File

The first step in performing a silent installation of CA Process Automation is to create a response file.

Consider the following notes about the response file:

Do not change the variable names as the installation uses the existing variable names.
Use forward slashes (/) as directory separators to specify folder locations.
Use the number sign (#) to comment out variables that you do not want to use.
See the following installation log to review errors:
```
${install_dir}/server/c2o/installation.log
```

Follow these steps:

Insert Disc 1 of the CA Process Automation installation media or browse to the location where you previously copied the installation files from the installation media.
Open the DVD1 folder.
Open the following file.
```
response.varfile
```
Provide the appropriate parameter values.
The varfile includes parameter descriptions. For example, to enable CA EEM to use the NTLM protocol to authenticate CA Process Automation users, use the following setting:
```
enableNTLM=true
```
Required parameters can be found here.
Save the varfile to the path that contains the silent installation script file.
The response file is created.
