NVU Install / delete problems

Problem #1:

I downloaded Nvu Portable 1.0 rev 3 and tried install it on my 2GB flash stick into the folder G:\Program Files\Nvu . It didn't work. I even tried it on multiple pc's. I get a error:

Problem #2 | I cant delete

Since it didn't install properly on multiple pc's, I went to go delete it. I get prompted with this:

Thats odd. Why are there boxes in the filename....
Then I get this....

So i try to delete the files manually. In the G:\Program Files\Nvu\NVUPortable\App\nvu folder is the location of the odd files names. Not only that, it says the total size of the folder is 10.5GB. When I try to delete those files I get...

Note that awfully large files on my 2GB stick...

I need help of getting rid of those files and or fixing the bad install.
