I did upgrade to PeopleTools 8.54 and received this error “PS/nVision was unable to start communication with Microsoft Excel (28,82).”
This error remained the same irrespective of running nVision in 2-tier or 3-tier or 4-tier mode.
Depending on the PeopleTools version you’re running, there are several possible reasons for this error. They are listed below.
How to resolve “PS/nVision was unable to start communication with Microsoft Excel (28,82)”
- If you also upgraded to PeopleTools 8.54 or higher – the likely cause of the error is that you might be having Microsoft Excel 32-bit installed. From PeopleTools 8.54 onwards, you need 64-bit install of Microsoft Excel if using Excel Automation. Three different release of Excel, namely – Excel 2016, Excel 2013 and Excel 2010 are supported, but 64-bit only. Most of the places still have 32-bit version of Microsoft Office installed but 8.54 nVision does not work with 32-bit.
- Make sure that 64-bit Excel is installed on the process scheduler server (so that nVision batch runs fine) as well as desktop of the users (so that they can access it in 2-tier and 3-tier mode).
- Make sure that your Microsoft Excel account is verified.
Sometimes Excel would have been installed correctly but due to network issue or firewall issue – your copy of MS Excel may not be active yet. To verify the same – open Excel, go to File -> Account -> About Excel.
If your Excel copy if active, you’ll be able to verify if the install is 32-bit or 64-bit.
Additionally, you can also verify the following:
- If the batch server is on a 64–bit Microsoft Windows 2008 machine, create an empty “Desktop” folder with this path:
- Verify that the PSHOME directory setting under the Process Scheduler tab is correct.
- Verify that the DBBIN setting under the Process Scheduler tab is correct.
- Verify that the directories defined under the nVision tabs are correct.
- You can uninstall and perform Install Workstation.
