I have NEVER installed Truecrypt and, I have only extracted it as portable version.
I do NOT have C:/windows/system32/drivers/truecrypt.sys and I have NEVER installed Truecrypt, yet CTM still complains that it cannot install because I have Truecrypt installed.
I DO NOT have a partition encrypted with Truecrypt either. TC only creates a virtual drive (portable drive) if I run it, but even when I had TC not running and even though truecrypt.exe was not in memory, CTM still complained I had TC installed.
So CTM must have browsed through my C:/Program Files folder and saw TC inside there and decided it’s installed, when in fact it’s never been installed and not even running.
I don’t use CTM any more. I kept having problems with it on Windows 7. Seemed fine on Windows XP though. I think it kept telling me it had ran out of disk space even though there were a high percentage of space free. I can’t remember TBH.
When you run the initial Truecrypt program it gives you an ability to EXTRACT only and not install. So that’s what I did, I manually created a Truecrypt folder in C:/Program Files and then I manually extracted the Truecrypt files into that folder.
So Truecrypt is NOT installed, it’s just been extracted into C:/Program Files/Truecrypt folder that I manually created.
So CTM must browse through my C: drive and find the C:/Program Files folder where the Truecrypt files are in and falsely conclude that Truecrypt is installed when it’s NEVER been installed.
