Looks like you need to search the current user registry for OLMAPI32.DLL
e.g. HKEY_CURRENT_USER\Software\Classes\Wow6432Node\CLSID\{ED475410-B0D6-11D2-8C3B-00104B2A6676}\InprocServer32
C:\\Program Files\\Microsoft Office 15\\Root\\Office15\\OLMAPI32.DLL
and replace with
C:\\Program Files (x86)\\Microsoft Office\\root\\Office16\\OLMAPI32.DLL
Recently tried to login to my wordpress Dashboard and the backend looked like the attached Picture.
First thing I did is disable all plugins which didn’t fix the issue
Next I Reinstalled WordPress which fixed the issue
Upgrade VCenter
In order to ensure protection is not affected when upgrading or replacing a vCenter, the vCenter database should be preserved
Upgrade then make sure Replication all comes back green
Upgrade Hosts
Before Upgrading the Hosts to the latest ESXi , double check the current version of Zerto supports the version you are putting on or you will get the error on Upgrade “VRA unsupported esx version”
Migrate all VM’s to other VPG’s , migrate 6 VM’s at a time
Once VM’s migrated , shutdown VRA and VRAH , restart upgrade host
You can migrated VCC machines to other hosts without effecting replication

PreReq
Installation
Recently upgraded a IPV500 v2 phone system from Version 9 to 10 and had a phone stuck on
Discover xxx.xx.xxx.x
To perform a reset in the Craft Menu you can try clearing the phones values so that when it establishes DHCP again it’ll point to the PBX (as long as the port its connected to has a route to the PBX).
Reboot the phone and when you see the “Press * to program” screen, press it and try entering the passcode as (CRAFT) 27238#.. Thats the default so it may not work on all phones. If it works, scroll down to “Clear values” and select it.
Download the .tgz upgrade file from here https://www.citrix.co.uk/downloads/netscaler-adc/firmware.html
Save your configuration first ( remember this does not save automatically ) and backup a config backup.
If this is a virtual machine do a snapshot / chekpoint
Let’s get started with the upgrade wizard:
select the location for the firmware file:
Next, verify the licenses you have already installed these will work with the new netscaler and begin the upgrade.\
The upgrade will take down the gui first , then after the netscaler when it says rebooting
Other key things to note – the upgrade has turned back on SSLv3 support on the Gateway vServer…however, it has enabled support for TLSv1.1 and TLSv1.2 which was missing from the 8007.e release. Nice!
The new web interface will look like below
If you see a solid black screen after upgrade you will need to delete your cache or do a CTRL and F5
Note
Double check the SSL Profile on your virtual server make sure it’s set to : ns_default_ssl_profile_frontend
With SSL3 off and TLS 1.2 on , you can check via : https://www.ssllabs.com/ssltest/
Recently an Veeam Backup and Replication Software was upgraded from v8 to 9.5 , to fix an issue with Internal Database
Failed to copy item ‘\\network\Location’ Error: The filename, directory name, or volume label syntax is incorrect
this feature is not supported since version 9, so this might work but the product does not guarrantee this feature would work properly, and unfortunately we do not support features that does not supported by the version you are using.
please see this guide: https://helpcenter.veeam.com/docs/backup/hyperv/file_copy_source.html?ver=95
it says “You cannot use deduplicating storage appliances, shared folder backup repositories and shared folders as a source for the file copy job.”
This is annoying as it did work with Older Versions , in the end , I have to add \\network\Location\Folder ( extra folder on the end ) for the source folder instead of \\network\Location

The install should ask you to reload which will restart the whole stack ( All Stack members should run the same IOS )
If the SSH console disconnects during the install progress you will need to do an Manual Reload Command
