Windows Forum / Security / Internet Explorer Security / September 2008Run Unsigned Applications
I'm trying to install software from one of our vendors from a CD. During the installation, I'm getting this error message: ERROR DETAILS Following errors were detected during this operation. * [9/23/2008 3:23:47 PM] System.Deployment.Application.InvalidDeploymentException (Manifest) - Your Web browser settings do not allow you to run unsigned applications. - Source: System.Deployment - Stack trace: at System.Deployment.Application.ApplicationActivator.BrowserSettings.Validate(String manifestPath) at System.Deployment.Application.ApplicationActivator.PerformDeploymentActivation(Uri activationUri, Boolean isShortcut, String textualSubId, String deploymentProviderUrlFromExtension, BrowserSettings browserSettings, String& errorPageUrl) at System.Deployment.Application.ApplicationActivator.ActivateDeploymentWorker(Object state) It states that my web browser doesn't allow unsigned applications to run. I've tried all kinds of variations for the security settings and nothing seems to help fix this problem. Can someone please tell me which boxes to check or uncheck in IE7 Security Settings. Thank you! Always state your full Windows version (e.g., WinXP SP3; Vista SP1) when posting to this newsgroup, please.

I suspect the prompt is being encountered due to a software restriction policy which may have been put in place via Group Policy and/or the method used to deploy WinXP SP3 and/or IE7.

You might have incompatible add-ons: Go to Start | All Programs | Accessories | System Tools and click Internet Explorer (No Add-ons). 2. Tools | Internet Options | Advanced Scroll to the bottom and click Reset Internet Explorer Settings. Read this article first: How to use Reset Internet Explorer Settings (RIES): http://support.microsoft.com/kb/923737 Note that the Reset IE Settings button will delete AutoComplete data (such as passwords.) Do you have those backed up? 3.

For quite a few people it's by installing programs like Messenger Plus, whose ads for malware don't identify the malware as such and try to convince you that you owe it to the author.

Don't install any extras you're not sure of.

I'm going to try each of them until I get my problem fixed. Stellla > > I'm trying to install software from one of our vendors from a CD.

I followed step 1 and then step 2 if your possible solutions. When my problem still existed, I decided to look at the installation program again. That's where I believe the problem lay...instead of suspecting the browser security as the error message indicated. The vendor had 2 options for the install - (1) install Windows Installer 3.1 and .Net Framework 3.5 or (2) launch installation program (this step assumes you had the necessary programs. Well since I had the necessary programs, I was choosing the LAUNCH option and got the reported error message. When I clicked INSTALL button, it checked for the required software and then went into the program installation. I reported above to the vendor and hopefully they will get their act together. This was a good learning lesson for me and you gave me a lot of new insight into IE7. Thank you again for your help! > Thank you for your ideas.
