At the MATLAB command prompt, command

if ~exist('C:\Users\Rajan\AppData', 'dir'); mkdir('C:\Users\Rajan\AppData'); end
if ~exist('C:\Users\Rajan\AppData\Local', 'dir'); mkdir('C:\Users\Rajan\AppData\Local'); end
if ~exist('C:\Users\Rajan\AppData\Local\Temp', 'dir'); mkdir('C:\Users\Rajan\AppData\Local\Temp'); end

After that you should be able to use the software.

Change line 17 of tempdir.m to this:

dirname = pwd;

Please run this and report the output:

parts = {'C:\', 'Users', 'Rajan', 'AppData', 'Local', 'Temp'};
if ~exist(parts{1}, 'dir')
    error('You do not have a C: drive. Giving up.');
end
failed = false;
for K = 2 : length(parts)
    thispath = fullfile(parts{1:K});
    if exist(thispath, 'dir')
        fprintf('Okay we already have directory %s\n', thispath);
    else
        try
            mkdir(thispath);
            fprintf('Was able to create missing directory %s\n', thispath);
        catch
            fprintf('Failed trying to create missing directory %s', thispath);
            oldpath = fullfile(parts{1:K-1});
            p = fileattrib(oldpath);
            fprintf('Attributes of parent directory %s are:\n', oldpath);
            disp(p);
            failed = true;
            break
        end
    end
end
if failed
    fprintf('problems creating directories. Not ready to use\n');
else
    fprintf('Okay, should be ready to use directory %s\n', fullfile(parts{:}) );
end

Could you show the output of

T=getenv('TEMP');
fprintf('|%s|\n', T); 
T+0
