./ROInstall_64
invalid command name "bind"
    while executing
"::unknown bind Text <Tab>"
    ("uplevel" body line 1)
    invoked from within
"uplevel 1 $next $args"
    (procedure "::obj::Unknown" line 3)
    invoked from within
"bind Text <Tab>"
    (procedure "::InstallJammer::InitializeGui" line 19)
    invoked from within
