Hello, I was installing ArcGIS 10.3 for Desktop and everything was fine, but then the installation was paused by this:
Retry didn't work, so I decided to ignore it. I think 3 or 4 same windows appeared next (only a suffix for that file changed) and I ignored all of them, The installation successfully ended and I was able to start ArcMap. Could this cause any problems? I have no idea what's this Tom Sawyer Software for.
