Hi Julian,
- Issue installing windows forms application on client machine. 'Cannot download application. The application is missing required files. Contact application vendor for assistance.' I clicked the 'Details' button and it showed this: PLATFORM VERSION INFO.
- The updates often include fixes to common problems. Download the latest free update. Open Reader or Acrobat. Choose Help > Check for Updates. Go to Edit > New > Key and create the missing HKEY_CLASSES_ROOT Software Adobe Acrobat Exe. Configure the web server to send content-type headers of 'application/pdf' for PDF files.
I recently was trying to reinstall windows 8 however when the process is about 10% complete, there is an error (Windows cannot install required files). I have already.
Thank you for posting your query in Microsoft Community forums.
I understand that you are unable to get an error message while downloading google chrome.
Before we try fixing the issue, I would suggest you to answer the questions given below.
1)Are you using Internet Explorer to download Chrome and Google Hangout?
2)Do you have any third party security software installed on your computer?
If you have any third party security software installed I would suggest you to disable it and check if the issue persists.
Disable third-party Security Software
a)On your Computer screen Task Bar next to System Clock..
b)You will see the third-party Security Software Icon.
c)Click on the third-party Security Software Icon, you will see a pop up.
d)In that pop and select the option to disable, click on it.
Now the third-party Security Software will be disabled.
Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
If the issue still persists, I would suggest you to contact Google support regarding this.
Hope the information helps, if you have any further queries, feel free to post. We will be glad to assist you.
My ClickOnce app gives an error for a user: 'Cannot download the application. The application is missing required files. Contact the application vendor or your system administrator for assistance.'
How can I pinpoit which file is missing? Do I manually need to put files on the publishing server?
I thought when I click on the prerequisities and set the option to download the prerequisites from the component vendor's web site and set to include components, ClickOnce would include all of them. Looks like I am missing something. How do I know what it is. Manually going through the manifest is going to be time consuming.

What I usually find on these issues is it's related to a dependency that is set as 'Include (Auto)' instead of just Include. It will work on some machines but not on others just depending on what DLLs are already installed on the destination machine.
Files to includeOpen up the Publish tab of your project properties and click on the 'Application Files' and then inspect which DLLs are set to 'Include (Auto).' You may need to change some of them to the standard 'Include' for things that are installed into the GAC on your machine. Visual Studio will make some assumptions based on your machine's configuration.
Log FileAnother thing to check is usually the error message will reference a text log file. I don't believe it links it in any way so you'll have to browse out to it. But find that file and it should give you some more information.
Certificate ErrorsOne problem that I have seen is if the SSL certificate that is installed on the server is not trusted on the machine you are attempting to install it on. I find this often for the GoDaddy SSL certifications since they are not always installed on machines who don't frequently use Windows Update.
ClickOnce is famous for displaying errors that have no relation whatsoever to the actual problem. If the problem is confined to a single user (which is what it sounds like), I typically first try clearing out the user's ClickOnce cache by deleting the %user_profile%Local SettingsApps directory. This will solve 80% of those 'Contact application vendor...' errors and is relatively low impact on the user's PC. They will simply have to re-download all of their .NET apps.
Is there a 'details' button when the error pops up? Usually there is a stack trace in there where you can see which particular file it is trying to download. Post that info here if you can.
