I appreciate the reply and insight. It seems to be something that is definitely out of my scope of understanding and I doubt it's something I would be able to tackle at this point in time. A little background on how this all works just to clarify. Accesstuner is the tuning software and the Accessport is the device that is used to communicate with the cars ECU. So the Accessport is able to data log and store the tune files for you to load onto the ECU at any point in time, while Accesstuner is used for adjusting the tune file and reading the data logs. I would think they assume that a tuner using their software is doing so on a dyno instead of the street and that they have access to internet either in the building or with a hot spot. But here is something I've tried and I can't say for sure whether this actually worked or not since I was afraid of opening the Accesstuner and it auto updating on me. So I had left my laptop in airplane mode, Accesstuner would not fully open because there was no internet access. But, the Accessport software which is separate would open up. Once that was opened it gave me a prompt to check for updates for the Accessport software. With this in mind I figured that the Accessport software had a function that allowed it to connect to Cobbs host for updates and that they would be similar enough but different in its functionality that I could share files between the Accessport and Accesstuner software. When I opened up the Accessport folder and looked over the files I found 2 .dll files that shared a common name with a variation in the numbers. I.E. (msvcp120.dll) and (msvcr120.dll) in the Accessport folder and (msvcp71.dll) and (msvcr71.dll) in the Accesstuner folder. Since these are both application extension files, I figure with my very limited understanding of software these files add a predetermined function to the software to perform an action. So I copied the Accessport .dll files and swapped them into the Accesstuner folder. I then turned my internet back on and opened Acesstuner. The program loaded, and I was asked if I wanted to perform an update and I chose no. The software fully opened and I was able to access everything normally. In the bottom right hand corner of the software it states that it is offline. So this could be a normal function of Accesstuner, and swapping those files could have done nothing/cause a problem I am unaware of right now. With that said Accesstuner did not update and I can still access the functions that were removed from the software that does come with the update.
