Use Windows (un)installer to fully uninstall WCG/BOINC

[romw]

Is it possible that the Windows installer/uninstaller asks to remove all traces of BOINC? Now when uninstalling BOINC through Add/Remove programs, the BOINC directory and entries in the registry stay in place.

What I would like is the option that some programs (games mostly) use, which ask you after you uninstalled the program if you want to delete the registry entries and 'saved files' as well. Of course this option should only be used when BOINC is uninstalled from the Add/Remove Programs program, not when upgrading it.

It gives that extra bit of finesse and service to the program

I have written a batch file that does the following:

1. Uninstall the BOINC user accounts and groups. [Use the Windows 2003 Server Tool NTRights.exe to delete the User Rights Assignments.[[br]([br]]
   2.)]
2. Kills boinctray.exe if it is still running.[Read the BOINC Install directory and Data directory paths from the registry and subsequently delete both directories and all files and sub-directories included.[[br]([br]]
   4.)]
3. Finds and deletes the BOINC_Master directory or directories in the Documents and Settings directory (works on foreign language Windows as well, where the "Documents and Settings" directory is set in that language)[[br]]
4. Delete all BOINC related keys from the registry.

It will assume that the user uninstalled BOINC through Add/Remove Programs first.
The computer needs to be rebooted at the end to finalize cleaning.

Setup bugs are being punted to a future release. This work item should be completed with the new open source installer.

Changing priority to Critical after the first Sony pre-installed complaint came in.

It's time the BOINC uninstaller came with the options of:

1. Leave the data directory, user accounts and registry settings alone.
   or
2. Remove any and all entries that were made by the software. Program and data directory, registry entries, Boinc limited user accounts, etc.

At least make these happen for the Sony installed World Community Grid installer.

David, what do you think? Is this an option in InstallShield?

[davidpanderson]

Don't know.

[Ageless93]

http://helpnet.flexerasoftware.com/installshield23helplib/helplibrary/RemoveFileTableSprt.htm shows how to do that (with InstallShield 2016)

We probably just want to test such an option, see how well it is warned that this will get rid of all of BOINC's files and folders. Or that there's extra warning text that can be added.

Scratch that. Richard had a good idea: offer a separate removal tool. Something like the script I had a couple of years ago that would remove all traces of BOINC from drives and registry. I'll look around if I still have that.

[Ageless93]

I still do. It runs from a batch file. This is just an idea. I think it misses one or two registry entries.
