Snap, just downloaded the g5_by_szcraftec.aswcs without problem.

What skins did you try to download ?
Did you get the error before the download completed, what was the exact error message ?

For example the g5_by_szcraftec.aswcs skin if you right click and choose ‘save as’ or ‘save link as’ depending on your browser, etc. you can choose the download location rather than the desktop, which on occasion can cause problems (not that I have heard this for the avast skins).

Double click on the file g5_by_szcraftec.aswcs and it should install it or you may have to indicate which program to associate (open) the aswcs extension “C:\Program Files\Alwil Software\Avast4\ashsimpl.exe”
