Uninstalling and Reinstalling

Uninstalling Sage 100 requires uninstalling each component separately. The server and workstation uninstall routines will remove all program files and registry entries made by the Sage 100 installation routines.

The program does not remove your Sage 100 data files. To remove these files, you must manually delete the MAS90 folder. All Sage 100 client workstation files are removed automatically by the workstation uninstall program.

Overview of Uninstalling Process

The installation process below describes all the procedures that must be performed to uninstall Sage 100.

1. If you are using Sage Fixed Assets, uninstall Sage Fixed Assets from the server and each workstation.
2. Uninstall Sage 100 from the Application Server and each workstation (see Uninstalling Sage 100).
3. Uninstall the Sage CRM software, if it is installed (see Uninstalling Sage CRM).
4. If you are using Web Services, uninstall it.
5. If you are using the Web Engine, uninstall it.
6. If you have no other Sage products installed, uninstall Sage Advisor. Do not uninstall Sage Advisor if you have other Sage products installed that use Sage Advisor to receive updates.

Uninstalling Sage 100

The uninstall program performs a complete deletion of all Sage 100 related files other than the data files; they must be manually removed by deleting the MAS90 folder.

If your system is integrated with Sage CRM, and you plan to continue using Sage CRM after uninstalling Sage 100, delete the linked Sage 100 companies before uninstalling. This will remove references to those companies from the Sage CRM database. For more information, see Delete a Company in the Help System.

To uninstall the server component

1. Ensure that all users are logged out of the system.
2. In the Windows Control Panel, click the Programs and Features icon.
3. Select the Sage 100 server component from the list. Click Uninstall to start the uninstall process. If you have more than one installation of Sage 100 on your server, each installation will be identified by its version or installation path.

   Important! If you choose to remove registry entries, you will be removing them from all installations of Sage 100 on the server.

   • All system files installed by Sage 100. This reduces the usage count of the shared system files, except for core components.
   • All files copied during installation
   • The program folder and program items created during installation
7. If you want to remove your Sage 100 data files, manually delete the MAS90 folder.

If there are any files that the uninstall program was unable to delete, a message appears stating that you can click the Details button to view a listing of the files and/or registry entries that could not be removed; otherwise, a message stating that the uninstall process was successful appears.

If you’re uninstalling Sage 100 as troubleshooting step and plan to reinstall, verify that the following files were uninstalled. Delete them if they remain on the system.

• In the C:\WINDOWS\SYSWOW64\ folder:
  • pvxio.dll
  • pvxsec32.dll

3. Click Uninstall/Change to start the uninstall process. When asked to confirm your selection, click Yes.
