How to Fix Sage 50 Script Error With Effective Solutions

If you are dealing with a script error when opening Sage 50, implementing the right troubleshooting methods can help run the software smoothly. Follow the troubleshooting methods in the same manner as listed below for smooth error resolution.

Method 1: Download & Install the latest service release

If you’re running an older release of Sage 50, compatibility issues with Windows may trigger script errors. However, installing the latest service release fixes known bugs.

  • Launch the Sage 50 program.
  • Choose Services > Check For Updates > Check Now.
  • Click the Download option.
  • Exit the Sage application.
  • Sage will automatically install the latest service release of Sage 50.
  • Reopen Sage 50 and check whether the script error has been resolved.

Method 2: Disable Sage Advisor Settings

Sage Advisor uses online services and background scripts that may lead to script errors in Sage due to connectivity or configuration problems. Therefore, disabling Sage Advisor may stop these scripts from running and help fix the issue.

  • Open Sage 50 application.
  • Choose the Help menu > Sage Advisor > Settings.
  • Ensure that all the boxes are unchecked and click OK.
  • Exit from Sage to save the changes.
  • Relaunch the Sage application.
  • Now, launch a screen from the Maintain menu. Then, see whether the issue still exists.

Method 3: Ensure that Sage 50 is installed in the correct directory

Installing Sage 50 in the correct directory enables the program to access the files and components. If you have a 32-bit operating system, then get the 32-bit version of Sage 50. The 64-bit version doesn’t work on a 32-bit operating system. For that, you can go to the Sage 50 download portal and download the correct version of the software.

Steps for a 64-bit system

  • Check the Sage program in the Program Files (X86) directory if you’re running a 64-bit computer.
    • For example: PROGRAMPATH=C:\PROGRA~2\SAGE\PEACHT~1\.
  • Uninstall the Sage 50 program if the wrong path is found.
  • Lastly, select the Preferred program file from the (x86) directory.

Method 4: Repair Sage 50 Application

A damaged or corrupted Sage 50 program may also trigger script errors. So, to fix the issue, you must repair the program to run the software smoothly.

  • Exit the Sage application.
  • After this, move to the program path.
    • To get the program path, right-click on the Sage icon.
    • Choose Properties.
    • You will see the program path on the Target line, minus Peachw.exe.
  • Now, rename the PTToday folder to OLDPTToday.
  • Copy the following path: “C:\ProgramData\Sage\Peachtree\”.
  • Paste the path into the File Explorer’s address bar and hit Enter.
  • Launch the V3xxx folder according to your Sage 50 version.
  • Next, delete the ProductServices folder.
  • Now, run the repair on Sage 50.
    • Right-click on the Start menu and choose Run.
    • Type appwiz.cpl and press Enter to launch the Programs and Features list.
    • Right-click Sage 50 and click Change.
    • Choose Repair and select Next.
    • Once the repair is done, click Finish.
    • Install the program updates as required.
  • If any antivirus is installed, disable it and reinstall the latest Service Release.
  • Finally, try to run Sage 50 and see if the issue is resolved.

Method 5: Turn Off User Account Control (UAC) Settings

User Account Control is a security feature that is used to keep your system safe from unauthorized access. But sometimes you need to disable the UAC settings to perform certain tasks in Sage 50. This will also help resolve the Sage 50 error messages.

  • Launch the Start menu and type UAC in the search field.
  • Choose Change User Account Control settings.
  • Now, drag the slider towards Never Notify.
  • Tap on OK to save the necessary changes.
  • Restart your PC to apply the changes.
  • Lastly, re-enable the UAC settings after completing the task.

Method 6: Add Sage.com to trusted sites

Adding Sage as a trusted site in the web browser will prevent the browser from blocking the Sage 50 application from running on your device. Perform these steps to add Sage as a trusted site.

  • Open Internet Explorer, select Tools > Internet Options.
  • Select the Sites button and click Trusted Sites.
  • Now, add the following sites to your browser;
    • Sage.com
    • Payrollonline.com
    • sync.peachtree.com
  • Finally, save the changes by clicking Apply and then OK.

Method 7: Enable the ActiveX Controls

  • Launch Internet Explorer, click Tools > Internet Options.
  • Choose Security > Local Internet > Custom-level option.
  • Browse to the ActiveX Controls and plug-ins.
  • Move to the previously unused ActiveX Controls, select Allow to execute without enabling prompt status.
  • Finally, hit OK for the confirmation.

Method 8: Rename UserPref.dat

If the above solutions don’t help, then try renaming the user preferences of the company to fix the script error in Sage.

  • Choose Maintain, Company Information.
  • Now, note down the location mentioned on the Directory line.
  • If any user has logged in to the company, then log out.
  • Move to the folder indicated in the Directory line.
  • Now, look for the USERPREF.DAT file.
  • Change the name of the USERPREF.DAT file to OLDUSERPREF.DAT.
  • Finally, try to log in to the company file again to see if the issue exists.

If you are also facing the following error “Assertion Failed: System.IO.FileLoadException: Retrieving the COM class factory for component with CLSID {22743F12-6056-4120-A3FE-98200361EF91} failed due to the following error: 80131040.” after going through the Script Error, see Error: “Assertion Failed, Abort, Retry, Ignore” when opening.
