First -- thanks for making this available and doing what is obviously a lot of work setting up an install. I'm new to this forum and set it up without any problems on a laptop with WinXP-Pro SP3. The instructions were perfect. Everything working including the WX updating properly via wireless. Now for the headache . . . I've got a desktop box running WinXP-Pro /x64 SP2 and I'm having the infamous: error message. Been through everything Ambo and Lancelot did . . . still getting that message. I was able to get the "5744" version working briefly with VAIO, but AVG 8.0 does not like hidec.exe. I see references to nLite in reading the "manual" install instructions. I've used this for slipstreaming /x64 SP2 into my /x64 SP1 distro, but little else. Would nLite work for getting it onto the /x64 machine without the error message . . . without needing the /x86 tskill.exe? Is there a thread you can point me to that has information about how to embed Alky and the Sidebar using nLite? I presume I'd have to also slipstream all the .net installs, IE 7, WMP 11, C++ runtimes, etc. Checked the nLite site but it doesn't have much there (that I could find). Thanks! -- John P.S. -- As I understand the history of WinXP /x64, it was created from the 2003 Server /x86. Shortly after that it started to branch into 2003 Server /x64 and XP-Pro /x64, but only briefly. The branching was pulled back together and now they're one and the same . . . two names for exactly the same O/S . . . likely because MS couldn't see the point in allowing it to branch and be saddled with maintaining two XP /x64 configurations. As a last thought . . . the reason I'm a bit loathe to revert to /x86 on the desktop is /x64's stability . . . *much* better than XP /x86 Home or Pro has been (SP3 may help) . . . otherwise I'd be seriously tempted.
