Note: If you are running Version 10, SAP only offers 64bit SAP Business One Client.

1. Uninstall the following components from Windows > Control Panel > Programs > Programs and Features, if they are present on the system (whether 32-bit or 64-bit). Be sure to note the bit version before proceeding with the uninstallation.
   
2. (optional)Remove or rename folder:
   32bit Client: C:\Program Files (x86)\SAP\SAP Business One\
   64bit Client: C:\Program Files\SAP\SAP Business One\
3. (optional)Remove all files under %temp% folder.
4. (optional)Remove or rename SAP folder under Windows user profile:
   C:\Users\[Windows account]\AppData\Local\SAP.
5. (optional)Open Window Registry, remove SAP folder if it exists (please backup registry before deleting):
   HKEY_CURRENT_USER\software\SAP and HKEY_LOCAL_MACHINE\software\SAP
6. Reboot computer and login Windows as Local administrator user.
7. Go to the SAP Shared Folder at "\\[SAP server name]\B1_SHR" and select either the Client folder (for 32-bit) or Client.x64 (for 64-bit), depending on the version noted in step 1. Right-click the installer located at "\\[SAP server name]\B1_SHR\Client.x64\setup.exe" and choose Run as Administrator. Follow the on-screen instructions in the setup wizard to complete the SAP client installation.
8. After successfully installing the SAP client, launch SAP Business One as Administrator for the first time. Log in and allow the system to automatically install all assigned add-ons by following the prompts in the setup wizard.

Note: To determine which version of SAP Business One client to use (32bit or 64bit) for older versions of SAP Business One, please follow the steps below:

• Verify the Windows operating system version. If it is 32-bit, you can only install the 32-bit SAP client. If it is 64-bit, proceed to the next step to determine the appropriate version for installation.
• Install the same version that was previously uninstalled or verify an existing installation on another workstation. The version is typically indicated in the desktop shortcut name. You can also find this information after logging in by navigating to Help > About SAP Business One. Alternatively, go to Modules > Administration > Add-on > Add-on Manager—if add-ons in the platform column are listed as x86, it signifies a 32-bit version; if they appear as x64, it indicates a 64-bit version. Ensure the SAP client installation matches the add-on version.
  . 
  
• If no add-ons are being used, either the 32-bit or 64-bit version can be installed. However, the 64-bit version is recommended, as it provides better memory management.
