I just uninstalled Stunnel version 4.53 and replaced it with 4.54 on my Windows XP SP3 x86 machine.
What I generally do is stop the service, uninstall the service, then uninstall Stunnel prior to installing the new version.
When I attempted to stop the version 4.53 service via the start menu shortcut, I was unsuccessful; all that happened was that the Stunnel status/log window would launch. This was repeatable. Likewise, when I attempted to stop it from an elevated command prompt using stunnel.exe -stop, the result was the same. I am administrator on this machine.
I launched services.msc, and was able to stop it from there without any difficulty.
After I installed 4.54, just to see what would happen, I attempted to stop the service again using the same methods. Same result.. I just can't do it in the conventional manner.
I checked to ensure that there was only one Stunnel service/process running, and that checks out okay.
Not sure if others are seeing this issue, but thought I'd better let someone know about it.
Thanks for the new version!
Regards,
Thomas
