The new version of P11D has overwritten the previous version

When you install Sage 50 P11D v28 on a computer that already has v27 installed, you must change the program directory during installation.

Sage 50 P11D installs to the following directory by default:

• C:\Program Files (x86)\Sage 50 P11D\

If you don't change this directory when you install Sage 50 P11D v28, v27 is overwritten and you can't access it.

If you've installed v28 over the top of v27, you can no longer access v27. This doesn't prevent you from processing 2022/2023 benefits in v28, however we recommend you keep v27 available in case you need to run reports for the 2021/2022 tax year.

Back up any processing done in v28

If you've done any processing in v28 you need to take a backup of this now. You can restore this backup into v28 at the end of this guide so you don't lose this processing.

 NOTE: If you haven't processed any 2022/2023 benefits in v28 yet, proceed to the uninstall v27 and v28 section. 

1. Log into v28 as normal.
2. Click File then Backup and complete the wizard to take a backup.
3. Ensure you save this in a location you can easily locate later.

Uninstall v27 and v28

Although v28 has overwritten v27, files still in place within Windows mean v27 is still amongst the list of programs you can uninstall. 

Uninstall both of these versions of Sage 50 P11D. For help to uninstall, follow our guide covering how to uninstall Sage 50 P11D.

Locate the v27 directory

Your next step is to locate the original directory, or if this isn't possible create a new one for v27. This helps to ensure that you install this separately to v28.

1. On your keyboard, press the Windows key and R.
2. Type C:\Program Files (x86)\ and click OK.
    TIP: If you see the error "Windows cannot find.." check you enter the text, including spaces, exactly as in step 2 and try again. 
3. Check the folders in this location for the folder for v27. 
   • If you find this folder, take note of it's name then skip ahead to the Install v27 steps below
   • If you can't locate the original folder for v27, follow steps 4 and 5 to create one
4. Right-click within this location and click New then click Folder.
5. Name this folder Sage 50 P11D v27.

Once you've completed this, log in to v27 and enter your activation details. You can now click File then Restore and browse to the most recent backup you took in v27.

Once you restore this backup, check that it's up to date and all benefits are processed correctly. If any are missing, you must process these benefits again to ensure the data in v27 matches what you submitted to HMRC for the 2021/2022 tax year. 

You've now reinstated v27 and can access it any time you need to.

Your next step is to install v28 into a new directory. To do this, follow all steps in our Download and install Sage 50 P11D v28 guide. This guide covers how to install into a new directory for v28.

If you took a v28 backup at the start of this process, you can now click File then Restore and restore this backup. If you don't have a v28 backup already, take a backup of your up to date data in v27. Restore this v27 backup into v28 and your company and employee data is set up in your new version. 

You can now continue to process as normal in v28.
