User tries to start ANSYS 9.0 and receives the following error:

'Error in start up script'
'can't find package Itcl while executing
"package require Itcl"
(file "c:documents and settingsuserprogram filesansys incv##commonfileslauncherlaunchermain.itcl" line41.

What is causing this error?

If the user has TCL_LIBRARY and TK_LIBRARY set to a third party software, this error will occur.
Add the following lines to the paths and the launcher will run.


C:Program FilesAnsys IncV90CommonFilesTCLlibtcl8.4


C:Program FilesAnsys IncV90CommonFilesTCLlibtk8.4

Please note that the TCL_LIBRARY and TK_LIBRARY are environment variables which are typically set on a Windows machine via Control Panel>System>Advanced>Environment Variables.

This Solution also works for later releases....10.0...11.0. Replace the v90 with the appropriate release number.
