Thanks Chris,
I remove all pb17 references and its ok now.

Roland,

i don't have CCleaner but i remember it for next time.

The program CCleaner (previously Crap Cleaner) has the ability to delete items from the installed programs list. Then you can run the registry cleanup a couple times until it doesn't find any issues.

Hi Copetti;

   This is rare, but I had been in the same situation when testing Alpha & Beta releases of Appeon PB and then trying to install the GA version later on. Even though I did an "uninstall" of those previous release/version (and even sometimes when the uninstall completed successfully) - the O/S seems to think that its still there and the new installer won't run because it thinks the current version is installed.

    Here is what I have done in that this case to resolve the "catch 22" situation like this ...

1. Remove all PB 2017 folders via File Manager  ... "C:\Program Files (x86)\Appeon\PowerBuilder 17.0" and "C:\Program Files (x86)\Appeon\Shared" and their sub-folders.
2. Run REGEDIT utility and remove all PB2017 references (a bit time consuming)
3. Reboot your PC

After the above, I have been able to now install OK. The same for PowerServer.

HTH

Regards ... Chris
