IconPackager 5 is in beta and is available to Object Desktop subscribers only. I'm not sure what the upgrade path is to version 5 - it has something to do with when you bought version 4.
For anyone considering purchases, an Object Desktop subscription is much better value than purchasing single programs (depending on how many you want to use)
And you will need to make that purchase just to get other stardock purchases to work...
They push the Object Desktop purchase because none of the stand alone software products work properly and are in a constant state of beta with updates almost every day...
Just cut your loses, close your wallet and consider Stardock a lose...
Yes I have been suckered in to Stardock by Nice looking MyColors themes only to find out that I need to purchase other software for it to work right, load, uninstall properly or better yet the way it should..
Stardock software has more bugs then a roach motel..
