Sorry people, I have tried all the following:
1) download the file, double click to install, "corrupt file".
2) download the file, re-name file as .zip,double click to install, "corrupt file".
3) download file, re-name as a .zip file, place in the Bootskins file, double click to install, "corrupt file".
4) download file, re-name as a .zip file, moved into a new folder named as same, double click, "corrupt file".
5) same as above, open the Bootskins program, import the file' "corrupt file.
Our company IT people tried and they tried several different ways also, got "corrupt" file also (they tried what has been suggested on all the message boards too).
Sounds like the program still has some bugs to be worked out as not everyone has their systems set up the same. I will keep trying as the program does look like a good one (yes, I am a glutton for punishment, but I refuse to give up).Any other suggestions as I am sure I am not alone in this mess.
