It should work for manually installed software too, WPKG don't care
about the way the software is installed, as soon as you know how to
remove it unattended:

1. create a package for that old version which uninstall it (tms-4.6.3-uninstall):
   - negate the checks, to check that the software is not installed
   - run the uninstall commands in <install/>

2. put tms-4.6.3-uninstall in a test profile

3. install manually the 4.6.3 version on a test workstation

4. use the test profile for that test workstation

5. run "cscript \\server\wpkgshare\wpkg.js /quiet /debug /nonotify /install:tms-4.6.3-uninstall" 
   => it should remove the software

6. add tms-4.6.3-uninstall as dependency to package tms-4.6.4

7. replace tms-4.6.3-uninstall by tms-4.6.4 in the test profile

8. do some tests: with 4.6.3 uninstalled, with 4.6.3 manually installed

9. do more tests on more workstations

10. deploy

Regards.
