Program Just started getting tons of stack overflows with a whole new level of error

Alright, this is probably the biggest program i have ever written. I use task in it once so that on first run it will search all available files and folders for certain things. Everything works...well, did work. Now when i start the program after adding a few more features in. It is throwing stack overflow errors on things that never had a problem before.

My first one was right in the begging it threw on a simple return of,

return System.Environment.GetFolderPath(Environment.SpecialFolder.CommonDocuments)

i changed it to just return

public string BaseUpdaterPath { get { return "C:\\Users\\Public\\Documents"; } }

and it started working again.

it got alittle further into the program untill it runs a check to see if a specific path exists.

if (File.Exists(pathINI))

pathini is defined earlier as

string pathINI = (BaseProductPath + "\\" + Name + ".ini");

and baseproduct is

        public string BaseProductPath { get { return BaseUpdaterPath + "\\" + Name; } }

these are things that should not be breaking. My error is this

An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

with more investigation turns into this

        Source  Evaluation of method System.Exception.get_Source requires calling method System.Reflection.RuntimeMethodInfo.CreateDelegate, which cannot be called in this context.    string

I can only imagine this has something to do with threading and the initial search that I am doing if this is the programs first run time.

If i can provide anymore information that i may have overlooked in my details i would be happy to provide it. I have not seen errors like this before that don't really give you much to go off of.

I may just end up throwing up a splash screen during that initial search if it's going to keep causing problems like this and have the rest of the program wait on that task.

UPDATE

I just stepped through my program starting at different steps and i was able to get past that check it kept kicking it out at. Then i got to a different if(foo == bar) and visual studio did this strange thing where it popped up a little loading window and said evaluating BAR then killed the program with

has exited with code -2147023895 (0x800703e9).

wtf is going on lmao

Another update incase anyone runs into this. I have a product preselected when i started up the programming, i wrote checks in to accommodate this however....it blocked me from being able to see what is really happening.

I disabled some code and let the thing run and after a while i found this little bastard popping up on the console

    Exception thrown: 'System.IO.PathTooLongException' in mscorlib.dll
Exception thrown: 'System.IO.PathTooLongException' in mscorlib.dll
Exception thrown: 'System.IO.PathTooLongException' in mscorlib.dll
Exception thrown: 'System.IO.PathTooLongException' in mscorlib.dll

now i gotta track that down to wherever the hell it's throwing 5000 times and i should be good to go.

Update again if anyone cares.

I found out that even i caught and threw the exception away it was still getting stackoverflow in windows.old because they have tons of folders and files and i was running out of memory. My solution at this point is during the recursive file check to just discard anyfolder in windows.old. Cant think of a better way.

THE EPIC CONCLUSION...I AM A DUMBASS

i was having two properties check eachother

        public bool IsInstalled { get
        {
            if (DefaultInstalledpath != null || DefaultInstalledpath != "Not Installed")
            {
                return true;
            }
            else
            {
                return false;
            }
        }

public string DefaultInstalledpath
        {
            get
            {
                        else if(!File.Exists(pathTXT) && IsInstalled == true)
                    {
                        return "Discovering! Please Wait...";
                    }

.........

i don't wanna talk about the rabbit hole i just fell down
