How do I completely remove Sage 50 Accounts?

Created on  | Last modified on 


This guide explains how to completely remove Sage 50 Accounts from your computer, including removing files and folders that are potentially in use by other software.


During a normal uninstall of Sage 50 Accounts, certain files and folders are not automatically removed. This is because they are shared and removing them may prevent other software from working correctly.

Don't worry, if you need to remove all files and folders, for example to fix issues that persist after a standard uninstall, you can easily remove these manually. Let's walk through it.

NOTE: If you simply want to remove the software quickly, just complete step 2. This will remove the Sage software but leave behind any files that could be common to other software.


NOTE: Following these steps may prevent other Sage software from working and you may need to reinstall the other software. Before you continue, please check you can reinstall any other Sage software you use.

Before you start

If you intend to reinstall your Sage 50 Accounts software, you should first check your current software version and make a note of your activation details.

1 - Remove DSN and ODBC data sources

  1. Log onto the computer as an administrator. 
  2. To open the ODBC Data Source Administrator window:
    • 32-bit Windows - Press the Windows key + R then type ODBCAD32 and click OK.
    • 64-bit Windows - Double click on C:\WINDOWS\SYSWOW64\ODBCAD32.EXE
  3. Remove any entries for Sage Line 50 within the User DSN and System DSN tabs.

    NOTE: If you installed the separate 64 bit ODBC driver, you must also remove this from within C:\WINDOWS\System32\odbcad32.exe

2 - Uninstall your software using Windows

  1. Press the Windows key + R then type Control Panel and click OK.
  2. Click Programs and Features then find and right-click the version of Sage Accounts you want to remove then click Uninstall.
  3. Reinstall the software and try to recreate the issue. 
  4. If the issue is still present, repeat step 2 to uninstall all versions of Sage 50 Accounts then click Next.

NOTE: Once you've uninstalled Sage 50 Accounts, you can either rename or delete the accounts program directory. By default:

  • 64 bit operating system - C:\Program Files (x86)\Sage\Accounts
  • 32 bit operating system - C:\Program Files\Sage\Accounts

3 - Delete shared folders

CAUTION: Sage 50 HR uses the following folders to store data. If you use Sage 50 HR you must ensure you have a backup of the data before you delete the folders. 

  • For each of the folders listed below, browse to and right-click the folder, then to delete the folder click Delete.
    Folder name
    C:\Program Files (x86)\Common Files\Sage SBD
    C:\Program Files (x86)\Common Files\Sage Line50
    C:\Program Files (x86)\Common Files\Sage Report Designer 2007
    C:\Program Files (x86)\Common Files\Sage Shared
    C:\Program Files (x86)\Sage EBanking

TIP: If using a 32 bit operating system, these folders are found within C:\Program Files instead of C:\Program Files (x86).

4 - Delete shared Sage files

NOTE: If you're logged into Windows as an administrator and you receive Access Denied messages when trying to delete files, you should disable the User Account Control (UAC). UAC must be turned back on once troubleshooting is complete. If you can't turn UAC off, restart the computer in safe mode to delete the files.

  1. For each of the files listed below, browse to the file, then to check it's a Sage file, right-click the file > Properties > Version tab > select Company Name > confirm the company name is Sage (UK) Limited or Sage.
  2. If the file is a Sage file, to uninstall it, right-click the file and choose uninstall.
