Hello, I'm from germany, the only thing I need, is a texvc.exe for my mediawiki-Internet side. The Installation of 3.10 was possible. "ocaml" in the command-line delivers "execption env-error". The call of gmake under C:\Inetpub\mslroot\...\math>gmake delivers the following ocamlopt -c util.ml Corrupted compiled interface C:\Programme\Objective Caml\lib\pervasives.cmi gmake: *** [util.cmx] Error 2 What is wrong? Greetings from munich, the town of famous german beers Martin Schlederer
