Trying to install Visio Pro 2019 on a Windows 10 system.
Office Pro Plus 2019 already installed and working.
Failing repeatedly. Nothing seems to work.
This is all with volume licensing at a university using a KMS server.

The steps below are on a system with an excellent Internet connection.
Windows 10, virus detection off, firewall off, setup command
executed in a CMD window run-as-administrator.
The C: drive has 100GB free.


Suggestions welcome...


------------------------------------------------------------

Managed to install Office Pro Plus 2019 using
the Microsoft Deployment Tool (latest version) with config

<Add OfficeClientEdition="64" Channel="PerpetualVL2019">
<Product ID="ProPlus2019Volume" PIDKEY="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX">

Doing the /download step and then the /configure step.

------------------------------------------------------------
Downloaded Visio Pro 2019 image (ISO) from
Azure Dev Tools for Teaching
and got
en-us_16.0.10730.20102_VisioPro2019rC2R_retail_ship_c ombo_en-us_dvd.iso
as well as a key

Tried to install the ISO in the old-fashioned ways (MSI) and
immediately got error 301820-39 (2)
It said "System restart required". However as numerous others
have reported, restarting the system didn't help.

Tried to install the ISO using the Microsoft Deployment Tool
by mounting it as D: and using a config with

<Add OfficeClientEdition="64" Channel="PerpetualVL2019" SourcePath="D:">


<Product ID="VisioPro2019Volume" PIDKEY="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX">

with just the /configure step.

Immediatel got the error message
"can't be installed on the selected update channel"

Also tried with SourcePath="D:\Office"
got error code 30182-1011 (3)
"we weren't able to download the required file"

-----------------------

Gave up on the ISO. Tried to use the same steps for Visio
as for Office.

Eventually managed to run the /download step.
It created an Office folder with 1.67GB.

The config is
<Add OfficeClientEdition="64" Channel="PerpetualVL2019">
<Product ID="VisioPro2019Volume" PIDKEY="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX">

However, the /configure step keeps failing with error 301820-39 (2)
Again it says "System restart required". However restart doesn't help.

In case anyone else encounters this problem, there is a solution.
Basically, follow the instructions in
Install Visio - Office Support


Use the same login/password as for azureforeducation.microsoft.com


Use the product key you got from azureforeducation.microsoft.com


You download an executable of about 5.7MB. Running downloads and install Visio Pro 2019!
