Lets start with a few questions. You downloaded 126.96.36.199, installed and it stopped working so you installed 188.8.131.52 and same result, correct?
Close. 184.108.40.206 worked the last time I tried it before downloading 220.127.116.11. I've only looked at it briefly a couple of times, never really used it.
When you download, you get a MapTool-windows64-offline.exe which you run and get the little window with the MT and Launcher icons.
The files I downloaded are MapTool-windows32-18.104.22.168.exe and MapTool-windows32-22.214.171.124.exe, with no "offline" anywhere in the file names.
Do you still click this .exe to run MT after installation?
As an FYI, the exe with the RPTools icon is just the installer. It then creates separate MT & Launcher Icons in the start menu under a MapTool folder.
I hadn't realized that, so yeah, I was using the .exes I downloaded. (Bad habit from Mote, I guess.)
If you use these icons, do you get the same issue?
When I use those, nothing visible happens. Whichever one I use, I get MapToolWinLauncher.exe showing up under processes in the Task Manager.
Can you zip up the logs directory and email them to me? my gmail is JamzTheMan and MT is installed @ C:\Users\<USERNAME>\AppData\Roaming\JWrapper-MapTool
On the way.
Lastly, you can try and uninstall MapTool (there is an uninstall icon in your start menu), reboot, then install MT again. Usually, this fixes any issues. I've seen the installer not respond because a previous java process is hung and rebooting kills any hanging java processes (unless you are comfortable doing it manually yourself).
I killed all the MapTool processes in the Task Manager, and got the same results. It seems unlikely I'd get the same corruption on two separate computers at the same time, but I'll try uninstalling and reinstalling when I get home (the reboot isn't practical on the work computer right now).
Also note that I get the errors mentioned when running the Launcher .jar from the Zip file, in addition to the problems with the JWrapper version. And that, too, went from working on 126.96.36.199 to not working on 188.8.131.52 or 184.108.40.206, on two different computers, running different versions on Windows.
My but (and 20 years of IT experience) tells me the first place I'd look (if I knew enough about it to do so) is at this week's Windows Updates, but you obviously have far more knowledge on this than I ever will.
I'll let you know how the uninstall/reinstall goes at home tonight.
