Ensure that security software is not decompress the file for inspection and he repacks because that would invalidate the signature manifest.

This is the message I get when I try to install the latest version of DPS App Builder "application could not be installed because the Installer file is damaged. Try to get a new setup of the author of the application file. On my Mac.
I tried to uninstall and reinstall
Help, please!
What version of Mac OS do you have? I guess it's 10.6.8 which is not supported by the App Builder. You need to update to a newer version of Mac OS.

This XPI has a maxVersion of 6, it must be updated for Firefox 7.
You can save this extension on the disc and open it to supplant the maxVersion yourself if you're feeling adventurous.
If you don't already have it, download and install 7-Zip program - this is a file management program archive utility for Windows - free and open source.
http://www.7-zip.org/
Once 7-Zip is installed, right click the XPI file and select open with > 7 - Zip File ManagerOnce you see the content of this XPI, locate the file install.rdf .
Right-click the install.rdf file and select Edit & your text editor will be opened.
Locate ine em: maxVersion and modify as follows * 7.0 .
Then use file > save money... in your text editor and 7-Zip will ask you if you want to save changes to archive - don't use any compression if you are invited to this topic.To install the extension en you have on the local disk, you can use the file > open file... or simply the XPI to slip into the Firefox browser window.
You will need to test this extension to ensure that it actually works again in Firefox 7.

The error message happens chronically today.
It does not matter what I try to install the air file.
I uninstalled, cleaned the registry and all the usual things.
And then re-installed-with the same error messages

I got a response on another area of support.
And
Because I asked for help here-
I think it's the kind of thing to do to post the
steps that allowed me to correct.
I knew I had the latest Adobe air platform.
I felt that I knew that the download files were updated.
So-
What was one of the suggestions I've had -
Told to turn off the firewall and antivirus.
Instinct made me disconnect the machine from the router.
I continued and disabled all the protections I had put in place-
and watched as the first program installed air -.
Since before January.
Then put those protections back in line.
And re-attached the router line.
It doesn't seem to work now.

WMP has stopped working a few downloaded days ago new installer. When I try to use it, the message error "there is a more recent version pf WMP (11.0.6002.18311)... Not possible to use an older package (11.0.5721.5146) on the current drive. Could not find it in programs to uninstall. After researching, I deleted the registry files
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\Setup\Installed Versions\wmp.dll
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\Setup\Installed Versions\wmploc.dll
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\Setup\Installed Versions\wmplayer.exeand updated my service packs and I tried Microsoft FixIts for similar problems. In addition, the WindowsMedia11-KB936782 - x 86 - ENU hotfix package. When I try to install that, it does not have enough storage space. Someone knows how to fix this? Much appreication.
Step 2: To resolve this problem, delete the Windows Media Player database. To do this, follow these steps:
Usually, also, had to stop the WMP network sharing Service before you rebuild the library. Click Start, type services.msc in the search field and press ENTER. In Services, locate the Windows Media Player Network Sharing Service . If its status is started , double-click the service, and then click stop . Tim Baets

This add-on could not be downloaded due to connection failure
I scoured the support forums, but still no solution for this. Can someone show what they did besides the new > string xpinstall active set value true, which was previously posted, it did not work. I'm looking for a way to install themes to my persona. I tried a lot of different things, but so far nothing not working, this also happens on other sites, but my goal is just the setting for personas. I will not use 36 ff because it is very problematic to stay now with 35, have computer windows 7. Any ideas? Going through safe mode, this isn't a solution. Any other idea? Persona is part of the Mozilla schema so it worked and just recently noticed his does not work. I tried to disable adblock and it makes no difference. I have deleted the cookies/history, still NADA.
Hi dobydoby, it's probably a problem that is caused by the addon "Open Link in New Tab" you have installed. try again after you stop it...

Original title: uninstall the program... Error message says: this patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package__
I'm trying to uninstall Microsoft Silverlight. I used Windows Installer found in the control panel to delete, however, when I try to remove the program I get the error 'this patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package.'
The program itself shows is no longer in my program list, and when I visit the Silverlight Web site may not detect an existing version on my system. But when I try to download the latest version, that he says could not be installed because I need to remove the previous version first... I'm going in circles and get no where... I downloaded Revo Uninstaller Pro but it also had no effect... I'm stuck!
Hello
The issue of Windows 7 you have posted is better suited for the public on the Silverlight Forum. Please ask your question in the forum Silverlight Installation and configuration.
