Hi kyoshero
You might try AutoPatcher v5.7.56 from here -->
viewtopic.php?f=26&p=4988#p4988 -- it should run fine on Windows 7, it does on Windows 8. Don't overwhelm the program though by checking everything for installation, use common sense -- you might select 5 initially to make sure the installation goes well..?
AP 5x wont download releases so you'll need to copy over your AP 6x \modules folder, don't forget any rti(z) file from the root folder for each release you copied, ignore the 6x apengine rti(z). If the APUP 1.5.1 link ever gets fixed you will want to add it to the AP 5x folder as the release download manager -->
viewtopic.php?f=26&t=1271#p4218 -- don't know why the fact the link has been broken is being ignored, such is the way things have been around here for a while now, should it get resolved jump on it while you can. AP 5x & APUP work as a team, with AP 6x, the functionality has been combined into one program - sounds great in theory. Unfortunately there are too many bugs in 6x for me to recommend it to my associates (I've had them regess to 5x if it works for em), I was simply overwhelmed by the problems, many emails, and phone calls.
Copy Sweeper too (it's a great cleanup tool), know that it also requires the rti(z) files to function.
If AP keeps giving you guff you might try WSUS Offline Update, it's a solid program and I know once you get used to the complexity it can be a reasonable alternative to AP, WU/MU, and some of the other tools out there.
AP 6x is the future, so hang on until the code is cleaned up -- fingers crossed!
