Fix folder permissions in the Sage directory
- Browse to C:\ProgramData (or C:\Program Files (x86)\Common Files in version 2019 or earlier).
- Right-click the Sage folder, then select Properties.
- Select the Security tab.
- Click Advanced.
- Verify the user has FULL control for this folder, subfolders, and files.
- Note: Give the current user Full control if access is missing.
- Click OK until all windows close.
- Open the Sage 100 workstation client again.
Refresh Common Components and AutoUpdate files
- Close Sage 100 on the workstation.
- Rename or delete files in these locations:
- C:\ProgramData\Sage\Common Components (version 2020 or higher)
- Version 2019 or earlier:
- C:\Program Files (x86)\Common Files\Sage\Common Components (64-bit system)
- C:\Program Files\Common Files\Sage\Common Components (32-bit system)
- Remove these files if present (6.00 is an example; the applicable version is in the file name):
- autoupdater.6.00.ini or autoupdater.6.10.ini
- autoupdater6.00.payroll.ini or autoupdater.6.10.payroll.ini (Payroll 2.0)
- AutoUpdate.6.00.mas.Log.txt or AutoUpdate.6.10.mas.Log.txt
- AutoUpdate.6.00.payroll.Log.txt or AutoUpdate.6.10.payroll.Log.txt (Payroll 2.0)
- Restart the workstation.
- Start Sage 100 and allow Workstation Synchronization to run.
- Log in if no errors appear.
Manually update files if synchronization fails
- Identify files listed in the AutoUpdate log files.
- On the server, browse to the ..\Mas90\Home\Lib\_repository.
- Locate the latest product update or payroll version folder.
- Copy missing files to the workstation and overwrite existing files.
Create a Common Components folder for upgrade scenarios
- For version 2020 or higher, use:
- C:\ProgramData\Sage\Common Components
- For Sage 100 version 2019 or earlier, create the required folder in one of these locations:
- C:\Program Files (x86)\Common Files\Sage\Common Components (64-bit system)
- C:\Program Files\Common Files\Sage\Common Components (32-bit system)
Check antivirus interference
- Disable containment or virtual environment features temporarily.
- Example: Comodo Client Security containment can block AutoUpdate scripts.
