Bubble: Can you please repost the longer error report at a larger size so we can read it? I have no idea why you can't get the tabcal command to work...?
it show the same error message... http://i1031.photobucket.com/albums/y380/mac6gti/Capture1_zpse5304237.jpg
Have you checked if tabcal.exe lies in the system path? if you don't know how to check this type path cd ..\.. dir tabcal.exe /s in the command window and post the output. Path will tell you where the system will look for commands (in priority order). The dir command will show where tabcal.exe sits.
Your path covers the directory where tabcal sits on my system (C:\Windows\system32). I can't see the output from your dir command...
looks like there are 2 tabcal... http://i1031.photobucket.com/albums/y380/mac6gti/Capture2_zpsa0643c06.jpg
the line dir tabcal.exe /s We need to see the system response to this (remember to do cd ..\.. first)
Sorry, I missed your previous post showing tabcal in C:\Windows\system32 This WAS in your system path, so I'm afraid this doesn't explain your problem :-(
