To install multiple Windchill RV&S clients on a single machine
* 
For the purpose of illustration, this procedure describes how to install two Windows clients on a single machine: a Windchill RV&S 11 and Windchill RV&S 12 client.
1. Ensure that the clients are installed in two separate directories on your machine, for example:
Windchill RV&S 11 client installation directory:
c:/Program Files/client11/IntegrityClient
Windchill RV&S 12 client installation directory:
c:/Program Files/client12/IntegrityClient12
2. For the 12 client, create a .bat file with the following content:
@ECHO OFF

title client12
cd\

cd Program Files\client12\IntegrityClient12\bin

@REM Set the path to point at the 12 client install first.

set PATH=C:\Program Files\client12\IntegrityClient12\bin;%PATH%
* 
To access mksis commands, add the Windchill RV&S server path after the Windchill RV&S client path. For example:
set PATH=C:\Program Files\client12\IntegrityClient12\bin\;
C:\Program Files\Integrity\IntegrityServer12\bin\;%PATH%
@REM Set the MKS_IC_INSTANCE_DIR variable to specify the location
of the client’s ViewSet, Sandbox registry, and preference files.

set MKS_IC_INSTANCE_DIR=C:\Program Files\client12\homedirectory
3. To ensure that Windchill RV&S 12 man pages display for the Windchill RV&S 12 client, set the following variables in the .bat file:
@REM Set the MAN variables.

set MAN_CHM_INDEX=C:/PROGRA~1/MKSTOO~1/etc/chm/tkutil.idx;
C:/PROGRA~1/MKSTOO~1/etc/chm/tkapi.idx;C:/PROGRA~1/MKSTOO~1/
etc/chm/tcltk.idx;C:/PROGRA~1/MKSTOO~1/etc/chm/tkcurses.idx;
C:/Program Files/client12/IntegrityClient12/etc/siman.idx;
C:/Program Files/client12/IntegrityClient12/etc/imman.idx;
C:/Program Files/client12/IntegrityClient12/etc/isman.idx;

set MAN_TXT_INDEX=C:/PROGRA~1/MKSTOO~1/etc/chm/tkutil.idx;
C:/PROGRA~1/MKSTOO~1/etc/chm/tkapi.idx;C:/PROGRA~1/MKSTOO~1/
etc/chm/tcltk.idx;C:/PROGRA~1/MKSTOO~1/etc/chm/tkcurses.idx;
C:/Program Files/client12/IntegrityClient12/etc/siman.idx;
C:/Program Files/client12/IntegrityClient12/etc/imman.idx;
C:/Program Files/client12/IntegrityClient12/etc/isman.idx;
4. From a command line prompt, run the .bat file.
5. From the same command line prompt that you ran the .bat file, start the client you want to run.
* 
If you start the client from a new command line prompt, the variables set in the .bat file are not read.
* 
You can also choose to create a similar .bat file for Windchill RV&S 11 client.
