Oliver, One last observation I have made regarding this bundle installer. The reason for all the size calculations is that the installer and code are offset a specific bytes within the file. Even if I correct the shell calls the file size will change and the code will not be extracted correctly. However, I can open the file and find exactly where the code is located, extract it and place it in the location where the shell script would place and see if it will run from there. This is a longshot but the fact is shel= l scripts automate what can be manually performed. But, using vi will be tedious. Gedit will not open the file. Are there any other very forgiving editors that will make it easier to edit this file? Thanks again.
