@Siginet: for now I used your suggested "fix": let it check for a RunOnceEx.cmd file (as the vast majority uses this name) and if it doesn't exist let it write the title, with a /f. BUT... I was thinking... would it also work WITHOUT a title? Can't test right now, I'll try to do that this weekend. Unless somebody else could? @djbe: I'm ASTONISHED............................... Anyone's got a clue how to fix this? With the original script (by idle.newbie), it did not have this problem. And afaik I did not make any large changes.... @sleepnmojo: THANKS! I'm ASHAMED I forgot that! @mark49: thanks for that suggestion. I've used it, but I omitted the '/WAIT'. What would the use of that be??? @sleepnmojo: thanks again... That was definetely a big typo... @djbe: thanks for that new version. @all: I'll post a new fix within a couple of minutes that fixes all problems that you can find back in this post. However, the problem with the OemPnPDriversPath won't be solved immediately, as I don't have a single clue how it's being caused...
