When you deploy the solution through visual studio, not only it deploys the solution but it activates the site level feature. If you are keep getting error, I would check what's causing site level feature activation throw an error..

Sure!

Please refer below links for stsadm command

http://technet.microsoft.com/en-us/library/cc263231(office.12).aspx

EX:

1) stsadm -o Addsolution -filename <<yourWSP file>>

2) stsadm -o DeploySolution -name <<solution name>> -url <<site url>> -immediate

Hi,

Are you deploying this feature from visual studio? use STSADM command and see if you get same error.

I would go to the central admin and manually delete the solution if it's errored out. Central Admin -> Settings -> Manage Farm Solutions would provide the info if solution was errored out. Try manually deleting it and redeploy through visual studio.. It seems like you have feature receiver for the site level feature and it throws an error while deploying solution from visual studio..Nik Patel

sorry very new to al this

stsadm is not recognised

If you are getting the error at the time of deploying the solution through VS 2010, first retract the solution through VS 2010.

Then it will be retracted from farm level and site collection level.

Then again you can easily deploy the solution. This time it will deploy smoothly.

Thanks Shiva

If you ever get the error, please run the Uninstall-SPFeature with Force on all the servers or boxes in the farm..

Retract and Deploy the solution and everything should be all right.. This happens whenever you install/deploy new solution on the environment where features are already installed/activated with previous version of deployed solution.. Proper retraction/deployment would help...

Just to build on what others have suggested...you can also just deploy the package with the -force attribute. Something like the following:

stsadm.exe -o deploysolution -name <wsp_name> -url <target_web_app_url> -immediate -force -allowgacdeployment

If you get "stsadm" is not recognized then you need to change directory to the <SharePointRoot>\bin subdirectory or add it to your path statement.

Old post but i can't see a direct answer to question 1.

Here it is :

Find the Feature with the given Id (in the output something like 57746904-90ae-4e73-8ad4-561a4df370e7) in the solution. Open the feature in Visual Studio.

From the Property tab (double click the feature), Change the property “Always force Install” to “True”. Deploy the solution again…

_{Saturday, May 25, 2013 6:03 AM}

The same same solution and feature already installed in farm and site collection.

First remove solution from farm.

Open the feature in Visual Studio. From the Property tab, Change the property “Always force Install” to “True”. Deploy the solution again.

1. Go to your Features in your project.

2. Open the feature.template.xml file

add AlwaysForceInstall="TRUE" to the below tag

Now try to deploy the code.

Thanks

If you are deploying from Visual Studio then please follow this post:

http://sharepointfordeveloper.blogspot.com/2014/03/solved-visual-studio-issue-error.html

Open the visual Studio and navigate to the feature XML file and add the bellow attribute. AlwaysForceInstall="TRUE" The <FeatureName>.Template.Xml output would be some think link this. <?xml version="1.0" encoding="utf-8" ?><Feature xmlns="http://schemas.microsoft.com/sharepoint/" AlwaysForceInstall="TRUE"></Feature>
