Yes, I noticed it too. In winMe it also gives an incorrect path error in silent mode. I previously had the app installed in a dir with short name when I tested. But trimming the spaces does not help. I think I will have to dig up my dosname converter module, which will convert to something like: d:\docume~1\James\desktop\fishpi~1\h.reg
Maybe you could try that name for me?
Speaking of my dosname converter, you can download that here:
