I am very experienced on Pioneer Elite receivers and setup over many years. With the SC-68 I recently bought, I have inserted the AV Nav disc that came with it just to see what's on the disc & how it's organized. I did install the setup software to a windows XP Pro tablet with IE7 and had no problems at all, no failures and correct language. If you have Vista, W7 or W8 you may have admin rights or compatibility mode installation issues to deal with. The software itself has 2 language choices, Eng & French. No Japanese. I assume you bought your 1222 in US and have US version? The AV Nav that came with the 68 is version 2012.IV
I did not use the AV Nav to setup the SC-68 since I am very familiar with their setup anyway. so other than look at the disc and install & review the software, that's as far as I went with it.
What I can say to you is that you are spending far more time trying to figure out how to use the software than it takes to setup the receiver using the setup menu and a TV for the onscreen display
and it's not hard to get started with auto MCACC for a basic Symmetry preset calibration & EQ.
why don't you give it a try so you can enjoy your new receiver? you can always keep working on the software issues as you go in case you ever want to go that route.
just a suggestion & not meant just because you're new
I think it's great you're trying to learn the software & seeking help. I'm just thinking of the frustration of not being able to jump in & enjoy your "toy"
there are thousands of experienced Pioneer SC model owners and dozens of SC model threads so if you get stuck, there will be people ready to answer questions. The AV Nav hardly ever gets discussed, can't recall much of any discussion, frankly. You may get lucky and someone here can help you which would be great. in that case, if you do figure it out, you can be the one who helps us!
if you are having problems just installing it or it's in japanese only, you may end up having to call Pioneer since it's possible you have an international Asian disc. Just guessing. They would know for sure which version should be in the box
you may have to make time for that call. You may have a windows OS or IE setting issue that's interfering and the problem may be with your versions of IE & its language settings...you will need PC help in that case...just guessing & that's why you should take time to call Pioneer.
you do have my curiosity up so later this weekend I may try using the software and would be glad to help if I can.
