Hi all, I've been using WPI for quite a while now and it's a great tool. But lately, I'm having an issue with it. Yestrday I've decided to update my RIS image with the newest DP & updates/addons. But since the update, which was done on clean MSDN image of win xp sp3 vlk, im getting the following error everytime i run WPI: Could not create reboot file: File: C:\rb_config.js Error Number: 5 Error Description: Invalid procedure call or argument The thing is, I don't even use the reboot function. When the error appears, I also have an empty WPI Log. I had the history.js issue which was solved by running office 2k7 install from a batch after WPI, and this seem similar. My WPI folder is located in the reminst directory for it to be universal to all my images. I've attached the config.js & runWPI.bat which i use for the procedure. Would appricate some help, desprate here config.js RunWPI.txt
