I found User Account Control Problems in other forums but didn't see much in Premiere Elements, so I hope this helps others who may be having problems with 32 bit programs in a 64 bit computor. When I first got my 64 bit I didn't have problems.
Back in February I bought a Quad Core Desktop with Windows 7 64 bit. Haven't been on the forum for 7 months since I wrote in regarding importing video with the Pyro AV Link (Premiere Elements Tips and Tricks). I was having problems importing video which started after March 28 sometime, as that was the last time I didn't have a problem importing VHS. Took me a few months off and on to find out what worked.
I started uninstalling Windows updates and any programs I had installed back to that point in time. Checked after uninstalling each item. The capture screen would come up on a delayed basis but clicking on capture did nothing. Although no driver is required for IE1394 (so they say) I read where some people using the Legacy driver had fixed some problems, so I switched to the Legacy. Seemed to work great (for a few minutes).
I had even uninstalled and reinstalled PE7 but no difference. Finally I noticed a shield in the PE7 Desktop icon. Thats weird. Never had that before. Just decided to show up after I had done all of the stuff I mentioned. Turns out at some point in time since I've had the computor Windows 7 decided to flag my 32 bit program as misusing the 64 bit system. User Account Control. I never bothered too much with UAC and just clicked on the yes box wen it popped up asking if I wanted this or that to take control of my computor. I tried using the minimum setting for safety reasons, and then finally turned User Account Control off. Bingo! PE7 capture works again and still working.
While I am not recommending that people arbitrarily turn UAC off, this appeared to be my problem. I would recommed that they try turning it off before uninstallin a bunch of stuff. Having a restore point may or may not have been a fix for me. I think one of the Windows Updates caused the problem but I am not going to uninstall any more stuff at this point, I have not been back on the internet or installed any more updates in my desktop. I am going to use my laptop for internet and used the desktop for video.
I am guessing this could be a problem for any 64 bit systems trying to use 32 bit programs. IE: XP,Vista,Windows 7 64 bit. In Vista there is also Data Execution Prevention (DEP) which you can turn on or off, supposedly to prevent misuse of memory (as I understand it), but Win7 either doesn't have it or I haven't found where it's located.
Maybe this has been covered in the forum somewhere and I missed reading it. Hope I am not too confusing. Anyway, whatever feedback you guys have would be great.
Thanks for your answer, and I did check out the link you suggested. However, I have Windows 7 Home Premium as most people have I think, and the XP program was not available. I started with Vista and now have Win 7. I never could navigate around in XP anyway so am content to just leave User Account Control off.
Interesting side note to turning UAC off is that my desktop seemed to be using more of the CPUs, where half of them were "Parked" as I wrote in also about 7 months ago when I 1st got my desktop. I am pleased to say that video processing seems to go quicker with UAC off. Have to observe things some more to confirm.
I just thought if others were having problems after installing Windows Updates and leaving UAC off worked then they could possibly pinpoint a problem.
