Manual installation to support 2010 mode in SharePoint 2013

Many of our customers upgrading their SharePoint farms to the newest 2013 version.

The upgrade process sometimes takes a long time and some of the site collections remain in 2010 mode. This state is not supported by our product's installer, as it deploys the solutions to the 15 hive in case SharePoint 2013.

In order for the products to work you need it to be deployed to 15 and 14 hives.

The instructions to do it are as following:

1. If you have already run the installer, retract and remove only the product’s solution
2. Open the product’s installer with an archive program , like: winrar or 7zip
3. Extract the files from the archive to folder1
4. Under the path folder1\resources\2013 you’ll find wsp files
5. On one of your SharePoint Front-Ends open SharePoint 2013 Management Shell (under All Programs > Microsoft SharePoint 2013 Products)
6. Perform the following commands on every wsp file:
   1. Add-SPSolution –LiteralPath [Path to wsp]
   2. Install-SPSolution -Identity [wsp file name] -GACDeployment -CompatibilityLevel {14,15}
      1. Some of the solutions have web application resources, in this case you’ll receive an error in the previous command, run it again with the –AllWebApplications switch
7. On every one of your front-ends, open command prompt and execute the following commands
   1. Cd “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\bin”
   2. Stsadm –o copyappbincontent
