Extraction of Installation data downloaded failed

[amaazouz]

Hi support,

I'm using IA 7.5 and tried to use the Web media blocks.
1- I Built my project using 'Web Deploy'
2- The 7zip are generated correctly containing all the specified files.
3- I copied the 7zip files on my server (that was already configured to accept the 7zip extension)
4- I used the generated setup.exe file to installa my application.
5- My web media blocks was downloaded correctly but has failed when began extracted with the following message 'Extraction of installation data downloaded from the web has failed...', both the 2 proposed option gives the same error message.

See attached file.

Did I miss something? What to do?

Thanks in advance for your help.

Download the 7zips in your favorite browser and tell us how big the downloaded files are.

[amaazouz]

The size of the 7zip file is only 4.1 KB.

[amaazouz]

1- 4.1 KB for the first one.
2- I have 16 in total, the biggest is around 17 MB
3- The compression is set to BEST (I tried NONE. It gave the same result)

So you still think your web media block downloads are being served right?

[amaazouz]

Yes

Then I'm afraid you're not qualified to be using InstallAware. A certain basic level of observational skills ARE required. While it can be hard to quantify or qualify the exact skill set, I can assure you that if you cannot observe file size changes, this does disqualify you.

What do you mean by NOT qualified to be using Installaware!!?
How can some features DISQUALIFY someone!?

Also, I think it was a misunderstanding: what were you meaning by 'So you still think your web media block downloads are being served right?'

I have discovered that if the Installer can't locate the correct file within the 7zip archive you will get an error message saying it could not install the said file (or something similar).

I would try copying the setup.exe file into a temporary directory as well as all the web media block 7zips into the same directory. If you then run setup, your program should install properly.

If it installs OK then the 7zip files are OK. It follows that IA is not downloading the correct 7zip files so have a look at your paths etc.

Thanks glenharvy for your reply.

I removed, from my 7zip files collection, one web block than contains files with non ASCII characters (in their contents not their names !!?) and all worked as expected.

Then I'm afraid you're not qualified to be using InstallAware.

I've read through this thread several times to see if I somehow missed the joke. Michael Nesmith can't really be serious can he?

You might as well say that anyone dumb enough to buy this product (includes me) isn't qualified to use it. I bought it and I struggle using it, so the problem must be me, right Michael? I say you're not qualified for tech support if this is how you "resolve" your clients' problems.

Hi InstallAware support,

I'm also getting this error. Basically, I just followed the instructions about "Web Media Blocks" on this link: http://www.installaware.com/installawar ... dotnet.pdf. The installer was able to detect the missing application runtimes and was prompted accordingly. When came the part where the installer tried to extract the downloaded .7zip files, it displays the "Extraction of Installation data downloaded failed" message and I get this message over and over on either options that I select. Here are the application runtimes that I have included in my installer:

1. Microsoft .NET Framework 4.52 (x86 and x64)
2. Microsoft Windows Installer 4.5

These runtimes came pre-installed with InstallAware X2, thus the setup scripts should be working just fine and I assumed that there's no need to make changes to those files. Under the "Web Media Blocks" branch, I specified the URL where I put the .7zip files that InstallAware itself had created (the server where I put it has no restrictions with .7zip files). I got the "extraction" message under these settings, so I tried some workarounds, like installing 7Zip application on the user's machine then extracted the contents of the generated .7zip files and compress it back again in .zip format this time. I'm still getting the message. I hope the workarounds that I did would be enough to "qualify" me to use your software.

Dear Marvin,

it's not necessary to use any workaround or to install 7zip Runtimes on the target machine and even, to manipulate the zipped block Archives.

First of all, I suggest you to try the following steps to verify if there is a possible issue with the package itself.

1- full rebuild your project including web media blocks.
2- Copy the entire WEB folder (your_ia_project_folder\release\web) to the target machine where you want to test your package.
Once the build process is completed, the Web folder will contain the generated setup package along with all the required Web Media Blocks)

3- Run the installer on the target machine directly from the WEB folder copy. By default the installer engine will try to use the web media blocks available in the setup.exe folder.

4- Finally test if the install process completes correctly.

Regards
