ISSUE
After installing recent updates, you might see one or more of the following errors when you start Outlook, Word, or other Office applications:
-
“The required file pagelayout.dll cannot be found in your path. Install Microsoft Outlook again.”
-
“The required file msls70.dll cannot be found in your path. Install Microsoft Outlook again.”
STATUS: INVESTIGATING
The Office Team investigation so far has shown that this issue occurs when the Office version does not match the Office channel. For example, this issue may occur if you are on the Monthly Enterprise Channel, but the version of the Office application is the Current Channel's version. Make sure that the channel you are on matches the version showing for that channel on Update History, Update history for Microsoft 365 Apps (listed by date). To see the Office version, open Word and select File, Account, under About Word. If there is a version mismatch, then there is a problem with the deployment configuration.
The immediate solution is to move to the channel that matches the Office build. The issue may be mitigated by uninstalling and reinstalling Office. If you need help working through the issue, please open a support case with the Office Deployment support team.
For those that have support cases open, please collect the two sets of Office Logs and the file information below and share them with your support engineer.
-
Close all Office apps, and then zip up the logs in this directory and add to your support case:Logs: %temp%/diagnostics.
-
Download the Microsoft 365 Apps Deployment Log Collector from the Official Microsoft Download Center. Once downloaded, extract it to a folder, run it, and then add the zipped-up logs to your support case,
-
Capture a screenshot of the Word version details. Go to this folder: C:\Program Files\Microsoft Office\root\Office16. Locate Winword.exe, right-click on it and select Properties, then select Details, and take a screenshot to add to the support case.
-
Capture a screenshot of the msls70.dll and pagelayout.dll version details in the same folder as noted in step 3 and add to the support case. In some cases, the version may not be listed but we still want to see that information. If the files are not present in that folder, that needs to be noted in the case.
