Cannot open any more databases error 3048

Daniel's right and I really only want to reinforce the importance of what he said.

Turning off Malware protection is not a viable solution in the overall threat climate today.

In our recent AUG Access Pacific meeting, Juan Soto, who was our presenter for the evening, told us that very few of his clients had been hit by this particular bug because he encourages them to stay on the Semi-Annual Channel.

The rollback does look daunting.

and typically, there are 57 different methods and they are all half baked. [exageration mine]

For me the Office Depoyment Tool with a config.xml did not work.

In the end I manually turned off automatic updates and now use a batch file to install the precise build I want

C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe /update user updatetoversion=16.0.[Build Number]

eg

C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe /update user updatetoversion=16.0.13801.20266

OK all security is back on.....thank you all for your concern.

Tried every Rollback instructions I can find, including Microsoft's, KentGorrell's batch file, and many others I've found. None of them take.

_______________

My version is:

Microsoft 365 Apps for Business

Version 2201 (Build 14827.20158 Click-to-Run)

Current Channel

_______________

I set up the Microsoft Config.xml as below:

<Configuration>

<Updates Enabled="TRUE" TargetVersion="16.0.14326.20738" />

</Configuration>

When I ran the setup.exe then click update from Excel/Account I get 'You're up to date - The latest version of Office is installed on your computer'

It doesn't even try looking for the requested version.

_______________

KentGorrell's looks the more likely to work as my version is:

This was my Batch File (Run as Administrator):

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.14326.20738

With this one I get: 'Checking for Updates' then 'Something went Wrong - Error Code: 30183-27 (400)'

_______________

Tried this Batch File (Run as Administrator) that I found from another website:

cd "C:\Program Files\Common Files\microsoft shared\ClickToRun"

OfficeC2RClient.exe /changesetting Channel="Semi-Annual Enterprise"

OfficeC2RClient.exe /update USER displaylevel=true forceappshutdown=true updatepromptuser=false

OfficeC2RClient.exe /updatetoversion=16.0.14326.20738

With this one I get: 'You're up to date - The latest version of Office is installed on your computer'

_______________

I have been in registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration

Added the UpdatetoVersion key with Value data set as 14827.20158

With this one I also get: 'Checking for Updates' then 'Something went Wrong - Error Code: 30183-27 (400)'

_______________

I find it unfathomable why a simple rollback is so difficult!

"half baked", yep. frustrating isn't it.

and I forgot to mention how useless the 365 admin center is.

I resorted to a command prompt as admin then went to

C:\Program Files\Common Files\microsoft shared\ClickToRun

when I run

OfficeC2RClient.exe /update user updatetoversion=16.0.13801.20266

using my current build number I get "you're up to date". what does that mean? that build is far from up to date. What the message box should telll me is that "You currently have this build installed" or something like that.

when I attempt to install

OfficeC2RClient.exe /update user updatetoversion=16.0.14326.20738

which is the last good build that I'm aware of and the one most of my clients are now on as per this site

https://docs.microsoft.com/en-us/officeupdates/update-history-microsoft365-apps-by-date

takes some time checking then...

I get Error Code: 20183-27(400)

the 400 is standard web error suggesting a bad request

my guess is that the build requested is not available despite the fact that it is still listed on the above site

but MS are too lazy to provide a meaningful response.

the recommended action is to run a fix for Office

Fix Office update errors ("Office"? I don't have Office, I have Microsoft 365 don't I?)

nomenclature aside...

Tried that, still doesn't work

at least they didn't tell me to reinstall windows then office, sorry 365.

also tried 2111 14701.20290 with the same result

Does anyone at MS bother to test this stuff?

Apparently no, that's our job.

I could try some more of the builds listed but I'd rather not wreck my own Office, sorry 365, install.
