I've got a strange problem regarding accessing a file (more specifically SnippingTool.exe) in Windows 7's System32 directory. I can see/run/access the file when opening the directory in Explorer (and the command prompt), I can copy it to other places (and it will be perfectly accessible in other locations), but when trying to access it in any way from other applications (examples include mintty, Notepad++ and a Java program), they simply report it as not existing.
I've noticed that this applies to many other files in System32 as well.
My problem is very much like the one posted here except this isn't about files I have copied into the directory, it's Windows' own files. This only happens on one of my computers (but it is the case on a friend's computer as well), the other happily lets all applications access the file, and I am absolutely clueless as to what is causing this.
Does anyone have suggestions for this? Both computers are running Windows 7 Ultimate 64-bit.
