Hello everyone,

First time poster I am hoping the can prove to be a resource to help us with a new issue that began over the weekend. We did patch our workstations this weekend so this leads us to believe it's related, but having trouble pinpointing the cause.

We are using Nav 2016, 9.0.44974.0. Users on their workstations have been utilizing the Export to Excel function on the Account Schedule Overview screen without incident forever and this past weekend are being greeted with:

We have repaired the openxml from the prerequisites folder in addition to fully removing and reinstalling the .msi from the Nav media. We also took time to do a complete repair install on the local computer of Nav2016 itself, but cannot restore the export to excel function to working order. Are there any suggestions as to what update just released could have impacted this? Windows 10/Office 2016 are the 3 machines currently failing that we are using as test boxes.

Thank you.

I did open a ticket with our partner and it turns out we re-ran the XML 2.5 on the server and still had no luck. We did a hard reboot of the server which then fixed the issue. Thank you for your help.

Hello,

Please also run this tool:

www.microsoft.com/.../details.aspx

These two options should resolve the issue. You did mention you did run some repairs already, but pobably the system did not repair the .NET Framework.

In case this does not work, raise a support request to Microsoft via your CSP / partner.

Thanks.

Hello,

Windows File Protection could be causing this. Here is a workaround:

Adjusting the folder permissions to explicitly deny the SYSTEM from making changes seems to have fixed it permanently. Below is sample of Outlook dll but you need get to do this on the DLL mentioned. E.g. Microsoft.Office.Interop.Excel.dll.

Thanks.
