None of the tools in my toolbox open properly. They show up as blank boxes with OK, Cancel, Environments, and Help buttons. I specifically need to perform IDW, which worked fine yesterday. I am away from my office and have a lot of work to do with a number of tools that normally work properly. This is not the first time I've attempted to use my tools away from the office, and they've worked fine every other time.
I've found a number of solutions by searching on google, mostly involving changes to regedit, but none have worked. Being away from the office, I am unable to simply reinstall ArcInfo. I know very little about this aspect of my computer and I really need help. Is anyone kind enough to talk me through this?
