Archiving fsx_sp1_ENU.exe problem

After downloading FSX Service Pack 1, My 1st action was to attempt to copy it onto a CD using winXp "send to" drive D. That didn't work, Got a "fsx_sp1_ENU.exe contains extra info attached to it that might to lost" [Retry or cancil]. Tried Windows explorer copy/paste, same result. I archive everything I download, I'm proud of my file and records sytem. Like the man said; "You didn't accomplish a thing until it's recorded". Has anyone backed Sp1 off onto a CD? Maybe burn a mirror image?

Addendium edit

Starting FSX right after installing SP1 crashed winXp (reset) . Probably the Sp install needs a reset.
SP1 install resulated in a lot of fragmented files, Disk Cleanup and Defrag fixed that.
1 of 4 of my saved flights causes FSX to restart. no big deal, other saved flights work fine.
The bird dog( https://flyawaysimulation.com/downloads/files/1427/fsx-cessna-l-19d-o-1d-model-305c-bird-dog-military/ ) survived Sp-1 installation and works better than before. 😀
ATC audio isn't on when the radio is turned off. 🙂
The engines in the Maule and birddog quit in the high res 3-D view after starting unless you crack the throttle open first. 😕
I see 25-35 FPS, cpu usage spikes to 98% whereas before it never climbed above 50%-60%, resource (memory) usage is the same around 1mb on winXp platform. 😂
