I have three different applications which suddenly stopped working with this error

Error #2046: The loaded file did not have a valid signature.

None of the sites has been touched in Months, I assumed they would keep working the way they had.

I wonder how many other sites are experiencing this and how many PO'd customers there are out there??

This is really bad business practice, what is causing it?

Note: the three were developed around the same time, one domain went down for a few days and was then renewed????

Daniel... have you found a solution to your problem?

I am also having the same problem. I was googling with no avail, when I noticed you added this post just yesterday,

so I am thinking that adobe has done something to the swz files hosted on thier servers.

Can someone from Adobe confirm if anything was done to either swz files or the crossdomain files on their end?

I am in the same boat as you... no changes on our side, but the application has suddenly stopped working.

We were building against a beta build of flex 4 (4.0.0.10485)

I wonder which sdk version you are using?

Here is what I see through the debugger...

Warning: Ignoring 'secure' attribute in policy file from http://fpdownload.adobe.com/pub/swz/crossdomain.xml. The 'secure' attribute is only permitted in HTTPS and socket policy files. See http://www.adobe.com/go/strict_policy_files for details.

[SWF] C:\Inetpub\wwwdata\xxxxxxxxx_Application.swf - 847,661 bytes after decompression

Error #2046: The loaded file did not have a valid signature.

Failed to load RSL http://fpdownload.adobe.com/pub/swz/flex/4.0.0.10485/framework_4.0.0.10485.swz

Failing over to RSL framework_4.0.0.10485.swz

Error #2046: The loaded file did not have a valid signature.

PS... I have tried multple PCs (XP, Vista, Server 2008) with different versions of flash player (10.0.45.2, 10.0.22.87)

Any help appreciated.

All three apps use framework_4.0.0.10485.swz

I think I was still using the beta when i did these.

To everyone that is having this problem... I think the right thing to do here is to let go of the beta sdk (4.0.0.10485) and build against a release version.

I am currently recompiling our app against 4.0.0 release build 4.0.0.14159 (I tried 4.1.0 but found it too difficult, and I dont have the patience on a Sunday)

That being said... I am 99.99% sure that someone at Adobe has broken the signing/certification of the 4.0.0.10485 swz file on their server - so, not happy

Totally out of nowhere.  Haven't made any changes to the site.

Migrating to Flex 4 "non-beta" is not an option, because there are a lot of differences in API from 10485 to 14159, and a one or two week downtime to work around those issues is not affordable for some applications.

There are two solutions, depending on how important are external libraries for your app(s), neither of which involves changing a single line of code.

  1. Disable framework RSLs and deploy a "fat" app
  2. Disable digest authentication for RSLs, and deploy the compiled framework SWFs along with your app. In this case, the old SWZ files are not interesting anymore, and you must deploy all the generated files, including the "framework.swf" etc.

Hope this helps for a quick solution of the issue.

Hi Savario,

The API had indeed changed (somewhat dramatically in some areas) from 10485 to

14159... but its not an impossible task, I worked on it 12 hours saturday and 12 hours sunday... and I was all done on a very complex app.

I think ultimately I had to take responsibility for using a beta SDK on our production server.

re:1) For me, disabling RSLs was not an option, as the application is pretty heavy and it would have pushed the total weight beyond acceptable.

re:2) Sounds like the best bet, if it works... when I tried it, I found that computers which had already cached the (incorrect) 10485 framework.swz would keep failing, even after it falls back on the framework swf... but now that I think about I am unsure if I tested the process correctly.

I think Johan is right; the 'signing' of the swz file was timed, and expired on the 17th.

Going forward, I am going to make sure that there is no dependancy on Adobe's server for the RSLs. That is the safest option; any problem that arises in the future will be caused by me, and I will probably have a better chance of sorting it out (and preventing it of course)

Hi

We face the same problems, too.

How do I advance the expiration date of the swz, can I know?

Wow 303 views in the first few days.

Adobe sure decided to waste hundreds, no make that THOUSANDS, of hours of its developer time to just delete a file without warning.

Wouldn't it be easier to give this another year and put the file back up or whatever?

Isn't the time of its developer community better spent...

I was using the beta to try and convince my company to embrace this technology.  My application being broken right in the middle of the evaluation is a deal breaker.  Even if I can fix this situation with a few hours of work, the idea of an enterprise depending on technology that can just stop working is a non-starter.

Even if you use Release version of the SDK, what will happen the same thing?

I am afraid to use RSL feature.

This is horrible. One of the veryveryvery few good things about Flash was that it always worked — if your player is was new enough.
