129.0. "uninstall of decnet breaks excursion" by EDSCLU::NICHOLS () Tue Feb 18 1997 16:13

I have uninstalled DECnet and PATHWORKS from one of my machines per the
instructions in the readme.  Unfortunately, my previously working
eXcursion no longer works.  I am getting an access violation in launch.exe.

The stack and some disassembly code are below.  I suspect that the DECnet
interaction with winsock 2 is the culprit, because our application no
longer works either.  Initially, I think WSAEnumProtocols() is returning
garbage, but Im not 100% sure yet.

(I guess this is the start of routine wxLaunchCheckTransport, I took the code
from that point on the call stack.  It is the first spot that had something
that looked intelligible.)

wxLaunchCheckTransport:

129.1	some system specs	EDSCLU::NICHOLS		`Tue Feb 18 1997 16:14`	5
	btw, this is intel, beta 2c pathworks and beta 2b excursion. I have not been able to get beta 2c excursion installed yet. There are no service packs installed. --roger
129.2	Run pws2dnst.exe to unregister DECnet	JAMIN::TELESETSKY		`Mon Feb 24 1997 16:47`	9
	The de-install intructions is missing a step. They should also instruct you to run pws2dnst.exe in the pw32 directory. This will unregister DECnet. What appears to be happening is that to eXcursion it appears that DECnet is still installed. It then tries to connect and fails. Marsha T. Feb. 24th, 1997
129.3	missing step for win95, wnt or both?	VMSNET::DMCFARLAND	still TurboMom[tm]...	`Tue Mar 11 1997 13:52`	14
	Marsha, Re: this missing step... I have looked at articles detailing the Remove Instructions for both Win95 and WNT 4.0, and it is not mentioned in either. Is this step needed for Win95, WNT 4.0 or both? At what point in the remove procedure should PWS2DNST.EXE be run? I am trying to do a review of these two articles in our STARS database and we need to be accurate. Thanx for your help, Diane
129.4	what i do	EDSCLU::NICHOLS		`Wed Mar 12 1997 08:02`	8
	>... At what point in the > remove procedure should PWS2DNST.EXE be run? I dont know how proper it is, but run it after deleting all the stuff from network->properties. --roger
129.5	still curious...	VMSNET::DMCFARLAND	still TurboMom[tm]...	`Wed Mar 12 1997 15:59`	9
	Roger, Thanx for your reply. But I am still curious: is this applicable for both Win95 and WNT? Also, is a reboot required between the time the stuff is deleted from Control Panel and the time this .EXE is run? Diane
129.6	still need input	VMSNET::DMCFARLAND	still TurboMom[tm]...	`Tue Mar 25 1997 08:43`	12
	Still looking for info on this. I have uninstalled PW32 on a Win95 and a WNT 4.0 wksta, yet I have never been able to find the file PWS2DNST.EXE. Is this part of the normal install? Or is it only there if you install one of the extras, like eXcursion? Please forgive my ignorance about this, but I would not like to advise a customer (possibly already distraught) that this .EXE should be run when I can't even find the file! Any input appreciated... Diane
129.7	my guesses	EDSCLU::NICHOLS		`Tue Mar 25 1997 10:48`	15
	Diane-- I only have Win NT, so I have no idea if pws2dnst.exe is part of the 95 kit. In my installs, this file is in the c:\pw32 directory. I dont reboot between control panel updates and running this. I suspect that eXcursion has little to do with pws2dnst since they live in separate trees. Maybe someone in the winsock or excursion group can be more specific. (And more authorative, remember I am only a user.....) I am guessing that the intallation 'registers' decnet as a transport with the general winsock api. This program then de-registers decnet during uninstall. Good luck, --roger
129.8		PEACHS::GHEFF	Got a head with wings	`Wed Mar 26 1997 15:18`	6
	re .6 Odd. I have pws2dnst.exe in my \pw32 directory. I do have eXcursion installed, FWIW, but that file is not a part of the eXcursion setup. #Gary
129.9	found it now...	VMSNET::DMCFARLAND	still TurboMom[tm]...	`Thu Mar 27 1997 11:27`	7
	Well, NOW I have the file, on both Win95 and WNT installations. The previous installations had field test stuff mixed in, and I probably did something wrong somewhere along the line. Thanx for all the input. Diane
