Can no longer open "extendtext.exe" after Windows update yesterday.

I've never had this issue. I've been using RMXP for about a year now with no issues and then suddenly this morning, I can no longer run "extendtext.exe" without getting this error. I had a Windows update yesterday and I'm guessing that's the cause of the issue since I've found 1 other person who is in my exact situation. Neither of us has found a fix.

If I can't fix this, I literally can not continue developing my game as the text field by default is just too small. so I'm really hoping someone knows how to fix this.
