Retired Redleg

No, I've got it set to close automatically after finishing cleaning. Running windows 10 Pro, 64 bit. AVG is my Antivirus.

Up until 2 updates ago, whenever I opened CCleaner Pro, it would open in a full window. Now however, for the last 2 updates, it now opens in a much smaller window that I have to expand. Is there a trick somewhere to 'Force' the full window, instead of the smaller one? Thanks

Have been using CCleaner for a couple years now, and Defraggler for a few months. Just got an email with the newest version, 1.03.094. Download went ok, as far as I know, but when I went to install it, I got an error saying something like "Cannot write to "C/ blah blah blah. The location I always use to install programs. I'm running Win XP Home, I'm the Owner, etc. I even went so far as trying to install it as Admin. Same problem, would not write to my C drive as it should. The last version installed just fine, and Works really good, so I know this should install as well. Any suggestions will be greatly appreciated, Thank you
