Yeah I remembered that issue from windows7 install back in the day,also the .dat or form files as well.
I've tried that,as well as changing the entire obd2tuner folder from read only,also the VDF's themselves before and after etc..
First it kept asking me for VDF when trying to open a .cal/.bin,then it started giving me path errors. Checking the folder most of my VDF's aren't even unzipping into the folder it looks like.
I have a small suspicion i'm not wiping all of it out when uninstalling. I keep seeing old files come up in the list of previous files when I go to open a .cal to test in TC. Since I just reinstalled there shouldn't be anything there.
Any suggestions for a clean wipe?
My IDS software is similar,if you don't get a full wipe and clear certain files/folders afterwards it will screw the new install.
