1. At the end of PRO/II 8.3 installation a dialog pops up asking for
Restart, with YES/NO buttons. If user clicks No button PRO/II
8.3 libraries are not registered with TDM. User needs to restart
before launching TDM from PRO/II 8.3.

2.PRO/II fails to launch with the default DEP setting on Windows
Server 2003. To correct this problem, right-click on My Com-
puter ==> Advanced Tab ==> Performance Settings ==> Data
Execution Prevention Tab.By default, the bottom radio button
"Turn on DEP for all programs and services except those I
select". To enable PRO/II to run, select the top button "Turn on DEP for essential Windows programs and services only. A
reboot will be required before this setting takes effect.
3. Hysis™ Translator is not supported on Network Install.
4. In order for PRU to work properly in the Network/ Newuser
install, the Newuser must be installed from a mapped network
drive.
5. For a Network Install on a Windows XP® SP2 or Windows 2003
Server, read/write permission should be set for all groups of
users.  Failure to do that may result in the PRU not working
properly.
Important information for uninstalling previous versions of
PRO/II
6. Uninstalling PRO/II 7.1 will disable the HYSYS® Translator in
PRO/II 8.0, 8.1, 8.2 and 8.3 if they are installed on the same
machine.  During the PRO/II 7.1 uninstall process, the
"Simulation Sciences\PROII key is completely removed.  The
workaround is to export the
"HKEY_LOCAL_MACHINES\Softwares\Simulation Sciences" keys
to a .reg file, and then re-import the file after completing the
uninstall.  This issue has been addressed as starting with PROII
8.0 so uninstalling PROII 8.0 or PROII 8.1 will not affect other
versions of PRO/II.
