When installing FD4 Beta 1 or 2, during the Flex SDK update, I get the error 'Download Cancelled'.
I've tried this with my Antivirus software (Nod32) on or off, seems to make no difference.
This happens on all 3 of my computers; 1 Windows 7 machine and 2 Vista machines.
I have UAC disabled on all my machines (like any sane person).

It seems to be the unzipping part of the install process that causes the hiccup, perhaps a temp directory is being denied access by windows? Could the FD4 folder be used as a temp folder instead? Am I talking rubbish?

What is the exact error message? Is it just "Download Cancelled"?

Mika could it be a timeout or something in NSIS?

It connects fine, shows me download progress and connection speed, then fails after finishing downloading the SDK.

Will try again tomorrow to get the exact error message.

Could you try the latest dev build to see if it works for you? I added a default timeout of 30secs for the downloader.

I too encounter issues with downloading the Flex and AIR SDKs from within FD4B2 !

No issues with getting the SDKs outside FD4B2 however!

The exact message is "Download cancelled. The installer will now continue normally."

Even with FD4-R2057 the SDK downloads fail, and the timeout happens after approx 20 seconds instead of the 30 seconds as mentioned earlier by Mika.

Are you using a proxy and what kind of internet connection you have? What firewall do you use?

I am behind a proxy and firewall, the details of which I am unaware of (Company managed & controlled). I do have a fairly fast connection (FD4 downloads in less than 5 seconds).

As I said earlier, downloading either FD4 or the Flex/AIR SDK separately/individually does not seem to be an issue, but trying to do it from within the install process always fails.

Is it possible to download and install the SDKs separately (out-of-band) and if so what is the procedure to install the SDKs and configure FD4 to use these SDKs?

Ok, this might be somehow related to the proxy and the firewall.

Yes you can download them seperately. You need to add the SDK path to Tools->Program Settings->AS3Context->Installed SDK's.

If FD4 had successfully downloaded the SDKs, where would it have extracted and installed each of the SDKs to?

To: FDinstdir/Tools/flexsdk/. If you have not specified a SDK, FD should add it on start.

This is still happening with FD 4.0.1 RTM.

It happens on 3 machines (two win7, one Vista) in 2 locations, I'm not behind a proxy in either, and in both places am just using the windows firewall.

+1 Downloads of Flex and AIR both cancelled at 100%. I tried at least 10 times today. At home, at work, the public library, and 2 internet cafes.
Windows 7 Pro SP1 64-bit, with and without completely disabled virus scanner (Eset NOD32 v4.2.71.2) and (firewall "Look'n'Stop v2.07").

Hi,

I'm new here but having used NSIS with downloads before, I would suggest trying the following:

Add /End to your download command:
NSISdl::download /TIMEOUT=30000 http://fpdownload.adobe.com/pub/flex/sd ... flex_sdk_${FLEX}.zip "$TEMP\flex_sdk_${FLEX}.zip"

Like so:
NSISdl::download /TIMEOUT=30000 http://fpdownload.adobe.com/pub/flex/sd ... flex_sdk_${FLEX}.zip "$TEMP\flex_sdk_${FLEX}.zip" /END

This has fixed the mentioned problem for me in the past.

Best regards,

Larod
